Title:

POLYCARBONATE-BASED THERMOPLASTIC RESIN COMPOSITION AND PROCESS FOR PRODUCING THE SAME

Document Type and Number:

WIPO Patent Application WO/2002/014428

Kind Code:

A1

Abstract:

A polycarbonate-based thermoplastic resin composition characterized by comprising a polycarbonate and a substantially gel-free polymer obtained by polymerizing an aromatic vinyl monomer in the presence of a polymer obtained by polymerizing a specific alkyl (meth)acrylate, an aromatic vinyl monomer, and a monomer having two or more unsaturated groups. The composition has excellent moldability (flowability, etc.) while having the intact mechanical properties (impact strength, etc.) inherent in the polycarbonate and has an excellent balance between moldability and mechanical properties. Due to the excellent balance, the composition enables size increase and thickness reduction in molded articles in various fields, especially in the field of domestic electrical appliances and housings for OA apparatuses. The composition is of great industrial value.
