This book elucidates the peculiar phenomenon of entropy/enthalpy compensation that takes place in high performance liquid chromatography (HPLC) of polymers. Numerous publications, including some books, are devoted to molecular characterization of synthetic polymers, materials presently produced in large and steadily growing quantities, applying methods of HPLC. A knowledge of the molecular characteristics of polymers is indispensable, not only for their proper applications but also for their recycling and remediation. Polymer scientists generally focus on synthesis and potential applications of polymers while not giving due attention to an important central link, their comprehensive characterization in context of development of structure-property correlations. To fill this gap is one of the aims of the present book. The process of entropy/enthalpy compensation plays a decisive role in the advanced method of polymer characterization such as liquid chromatography at critical conditions, eluent gradient interaction chromatography, and temperature gradient interaction chromatography. All chemists working on any aspect of polymer science will find this book a valuable resource for the development of structure-property correlations.

About the Author

Dr. Muhammad Imran Malik graduated from Karl-Franzens-Universit�te Graz, Austria, in polymer chemistry under the supervision of Prof. Bernd Trathnigg in 2009. Later, he worked in the research groups of Prof. Harald Pasch, University of Stellenbosch South Africa (2010–2011), and Prof. Taihyun Chang, POSTECH South Korea (2015), as a post-doctoral research scientist. The research focus of Dr. Malik in all above-mentioned positions was analytical polymer science. In 2012, he joined the International Center of Chemical and Biological Sciences, University of Karachi, as an assistant professor. The major research interest of Dr. Malik is synthesis of novel polymeric architecture and development of comprehensive analytical methods for polymers. His research interests extend to polymer stabilized nanoparticles and their applications, such as sensors, drug delivery, molecularly imprinted polymers, and organic solar cells. Dr. Malik has authored/co-authored more than 100 peer-reviewed publications, six chapters in edited books, and one authored book entitled “Advanced Separation Techniques for Polyolefins” along with one edited book entitled “Molecular Characterization of Polymers”. Dr. Malik also has one US and one Pakistan patent to his credit while three more are filed. Currently, Dr. Malik is an associate professor at the International Center for Chemical and Biological Sciences, University of Karachi.

Dr. Dusan Berek graduated from Polymer Institute, Slovak Academy of Sciences, where he spent his entire professional career. He was not allowed to leave Slovakia for a postdoctoral stay abroad. His studies concentrated on methods for liquid chromatography―separation of synthetic polymers, synthesis of column packings and role of enthalpic interactions in the separation process. He was able to defend his D.Sc. (Research Professor) Thesis in the Slovak Technical University, but only after the political change in the country in 1989. He hassupervised 15 Ph.D. students, three of them from abroad.

He was elected the scientist of year of Slovakia in 1999 for a set of published studies, Innovator of Slovakia 2001 for a patent licensed to a Swedish company and Academician of the Slovak Scientific Society in 2004. He has been active in Polymer Division of IUPAC, former European Chemical Federation, Slovak Chemical Society (president for two terms of office) and Central European Group of separation Sciences. He acted as the chairman of Czechoslovak and later of Slovak National Committee for IUPAC for 15 years.

Dr. Berek has authored or co-authored over 200 peer-reviewed publications (over 30 as a single author), which were so far quoted over 3,500 times, seven chapters in edited books, and he himself edited two books. He is an author or a co-author of over 60 patents, six of them were licensed to companies. Unfortunately, Dusan Berek passed on June 28, 2022 in Ljubljana, Slovakia, while he was there for a lecture in a conference.

Statutory right to withdraw

You have the right to withdraw from this contract within 14 days without giving any reason.

The withdrawal period will expire after 14 days from the day on which you acquire, or a third party other than the carrier and indicated by you acquires, physical possession of the last good or the last lot or piece.

To exercise the right of withdrawal, electronically fill in and submit a clear statement on our website, under "My Purchases" in "My Account". We will communicate to you an acknowledgement of receipt of such a withdrawal on a durable medium (e.g. by e-mail) without delay.

To meet the withdrawal deadline, it is sufficient for you to send your communication concerning your exercise of the right of withdrawal before the withdrawal period has expired.

Effects of withdrawal

If you withdraw from this contract, we will reimburse to you all payments received from you, including the costs of delivery (except for the supplementary costs arising if you chose a type of delivery other than the least expensive type of standard delivery offered by us).

We may make a deduction from the reimbursement for loss in value of any goods supplied, if the loss is the result of unnecessary handling by you.

We will make the reimbursement without undue delay, and not later than 14 days after the day on which we are informed about your decision to withdraw from this contract.

We will make the reimbursement using the same means of payment as you used for the initial transaction, unless you have expressly agreed otherwise; in any event, you will not incur any fees as a result of such reimbursement.

We may withhold reimbursement until we have received the goods back, or you have supplied evidence of having sent back the goods, whichever is the earliest.

You shall send back the goods or hand them over to moluna, Greven, Germany, without undue delay and in any event not later than 14 days from the day on which you communicate your withdrawal from this contract to us. The deadline is met if you send back the goods before the period of 14 days has expired. You will have to bear the direct cost of returning the goods. You are only liable for any diminished value of the goods resulting from the handling other than what is necessary to establish the nature, characteristics and functioning of the goods.

Exceptions to the right of withdrawal

The right of withdrawal does not apply to:

The delivery of newspapers, journals or magazines with the exception of subscription contracts; and
The supply of digital content which is not supplied on a tangible medium (e.g. on a CD or DVD) if you accepted when you placed your order that we could start to deliver it, and that you could not withdraw once delivery had started.
