Preparation and Properties of a Novel Thermosetting Resin Based on 4,4'-Bismaleimidodiphenyl Methane and Allyl COPNA Resin
Abstract:
A bismaleimide (BMI) resin system based on allyl condensed polynuclear aromatic resin and 4,4'-bismaleimidodiphenyl methane was prepared in this paper. The chemical structures and rheological properties of the resin prepolymer were characterized by FTIR and viscometer, respectively. DSC was used to study the curing reaction of the resin prepolymer, and TG-DTG was employed to study the thermal behaviors of the cured resin. Moreover, physical properties of the BMI resin, including mechanical and dielectric properties, were studied. The results showed that the BMI resin had good thermo-stability, good mechanical properties and excellent dielectric properties. Introduction
