Abstract
Abstract4‐Urazoyl benzoic acid groups were statistically attached to various hydrocarbon elestomers, polar elastomers and partially crystalline polymer via a polymer‐analogous reaction. Thermal analysis (DSC), infrared spectroscopy (FT‐IR), stress‐strain experiments and dynamic‐mechanical analysis were used to analyses whether these systems, analogous to functionalized polybutadienes, would form ordered supramolecular structures of the polar side‐groups that would lead to a thermoreversible crosslinking. While the structure formation is suppressed for elastomers with a large cross‐sectional area of the chain(e.g. butyl rubber) or polar side‐groups (e.g. polychloroprene), the mechanical properties can be controlled by balancing supermolecular structure formation and crystallization in the case of polyoctenamer.
