Abstract
The invention entails the combination of basic catalysts, specifically guanidine-based catalysts, such as TBD, in conjunction with functionalized amines having a hydrogen bond donating or accepting functionality, to facilitate the accelerated transamidation of polymer compounds with non-activated ester side chains.
Claims20
A method for the preparation of an amidated polymer, the method comprising:
- reacting a homopolymer or copolymer with a guanidine-based catalyst and a reactant (X) to obtain the amidated polymer,
- wherein:
- the homopolymer or copolymer comprises monomeric units;
- the monomeric units comprise at least two adjacent monomeric units each having an ester-containing side chain;
- and
- the reactant (X) has at least one amine moiety and a hydroxy moiety.
