HYPERBRANCHED ESTEROXAZOLINE POLYMERS

摘要

The invention pertains to a hyperbranched esteroxazoline polymer obtainable from a polymerization reaction of A-functional and B-functional compounds, characterized in that the polymer comprises a polymer backbone having ester and oxazoline groups and having hydroxymethyl end groups, wherein the A-functional compound stands for tris(hydroxymethyl)methanamine and the B-functional compound stands for a cyclic anhydride, or a dicarboxylic acid, or a derivative thereof; having a ratio of equivalents of oxazoline groups to 10 equivalents of backbone ester groups of 1:2 to 2:1, and a number average degree of polymerization Pn greater than 6.
