Structure-based nomenclature for irregular linear, star, comb and brush polymers with different types of constitutional repeating units (CRU)
This project is intended as a complement to the project 2013-031-3-800, “Structure-based nomenclature for irregular linear, star, comb and brush polymers,” which provides guidelines for the nomenclature of linear and branched polymers with three or more blocks that are of identical constitutional repeating units (CRU). This new project will provide guidelines for the nomenclature of the same type of polymers but, importantly, it will extend the nomenclature so that polymers containing more than one type of CRU can be easily and uniquely described.
In research and in industry, there is a need for clear guidelines for the nomenclature of such materials, both for articles and patents. On the one hand, recent developments in “controlled” polymer chemistry allow for greater control over polymer structures, and on the other hand, an increasing market demand for more complex materials, have together meant that polymeric structures are more complex and better defined. The current IUPAC recommendations can deal with most structures, but are increasingly becoming outdated, and in some cases, surpassed by the complexity of recently reported polymer skeletons. Source-based nomenclature has recently undergone a massive update. It can deal with most common structures; however, it suffers from its intrinsic incapability to deliver absolutely unique names for unique structures. This project will deliver recommendations for structure-based nomenclature which will be able to uniquely identify polymers and copolymers which contain a multiple number of CRUs in complex linear, star, comb and brush-based structures.
