FOAM AND FOAM PARTICLE FORMED FROM POLYESTER/POLYCARBONATE RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a foam and foam particles formed from a polyester/polycarbonate resin composition and being high in transparency and excellent in basic performances such as chemical resistance. SOLUTION: The foam or the foam particles are formed from the polyester/polycarbonate resin composition. The polyester/polycarbonate resin composition is prepared by melt-mixing a polyester with a polycarbonate and a polyfunctional component and has a controlled melt viscosity. Desirably, the foam or the foam particles have a single glass transition temperature between the glass transition temperature of the polyester and the glass transition temperature of the polycarbonate.
