Title:
IMIDE RESIN, METHOD FOR PRODUCING SAME, AND MOLDED BODY USING SAME
Document Type and Number:
WIPO Patent Application WO/2005/108438
Kind Code:
A1
Abstract:
An imide resin having excellent transparency, excellent heat resistance, low orientational birefringence and a sufficiently small optical elasticity coefficient is disclosed which can be easily produced at low cost. Such an imide resin is obtained through a reaction between various methacrylic resins and monomethylamine (or butylamine). Also disclosed is a method for producing an imide resin which is characterized in that a (meth)acrylate polymer or a (meth)acrylate-aromatic vinyl copolymer is treated with a primary amine. The imide resin has good heat resistance, transparency and processability, and thus is useful for a polarizer-protecting film.
