Abstract
Hyperbranched polymers and methods for preparing the same are disclosed. The polymers are obtained based on monomers synthesized via reacting a substituted or unsubstituted cyclic anhydride with a bifunctional amine.
Claims18
A method for preparing a monomer, comprising reacting a substituted or unsubstituted bifunctional cyclic anhydride with a bifunctional amine according to the reaction Scheme A:
- wherein:
- X is selected from the group consisting of a cycloaliphatic, an aromatic and a heteroaromatic moiety forming a condensed ring system with the furan ring of compound I;
- Y is absent or is selected from the group consisting of a C1-C15 alkyl and a C2-C15 alkylene moiety;
- and
- each of R1 and R2 is a moiety comprising a reactive functional group independently selected from the group consisting of hydroxyl, carboxyl, vinyl, allyl, acrylate and methacrylate, thereby obtaining the monomer II.
