Polymer material containing chains bearing imidazolidone functions

摘要

Polymer material (A) comprises macromolecular chains (I) (containing an average of 1-10 imidazolidone groups per chain) bound by hydrogen bonds, where (I) consist of a polymer skeleton whereon a modifying agent (comprising associative groups (imidazolidone heterocycle) bonded by hydrogen bonds and reactive groups capable of forming covalent bonds with the polymer skeleton, assembled in a common molecule) is fixed by covalent bond.
