Terminology of Polymers with Ionizable Groups and Polymers Containing Ions

Properties of several polymeric materials are related to the presence of ionic groups being either inherent fragments of polymer molecules or present in low-molecular-weight components of composite polymeric materials. The presence of both ionic and covalent bonds makes ionic polymers a very diverse group of materials, and their physical properties can vary from soft, pliable thermoplastics (e.g., ionomers) via rubbery elastomers to rigid, cross-linked materials (e.g., ion-exchange resins). The importance of this group of polymers stems from their widespread application in many areas of everyday life and industrial production.

IUPAC has approved a project to formulate clear concepts and definitions of terms related to the structure and properties of polymeric materials containing ionic or ionizable groups. The aim of this project is to eliminate the ambiguity and lack of precision often found in scientific and technical literature discussing chemistry and properties of ionic polymers.

This project is being coordinated by Prof. Przemyslaw Kubisa, a Titular Member of IUPAC’s Commission on Macromolecular Nomenclature (IV.I), with participation of other members of the Commission. Comments from the chemistry and polymer community are welcome and should be addressed to the project coordinator, Prof. Przemyslaw Kubisa, Center of Molecular and Macromolecular Studies, 112 Sienkiewicza St., 90363 Lódz, Poland; Tel.: +48 42 681 96 08; Fax: +48 42 68471 26; E-mail: pkubisa@bilbo.cbmm.lodz.pl.
