摘要

Abstract

Epoxy-terminated hyperbranched polymers (EHBPs) were prepared by proton transfer polymerization and characterized by FT-IR

H-NMR and GPC. The solution and thermal properties of the uncured samples and mechanical properties of cured samples were examined. The thermo-stable products had good solubility in polar solvents

low solution viscosity and

s ranging from 15℃ to 33℃ depending on their molecular weights. The mechanical properties of cured films were studied and compared with those of a bisphenol-A type epoxy resin. The films of EHBPs had good impact resistance and high gloss values without sacrificing hardness and adhesion.
