  • Stabilizer for compatibilized polycarbonate and polyamide polymer blends
    Patent number: 5187228
    Abstract: A monoglycidyl stabilized polycarbonate and polyamide blend comprising a polycarbonate, a polyamide, a polymeric compatabilizing agent and a monoglycidyl compatabilizing agent is provided wherein the monoglycidyl stabilizer effectively end caps the polyamide without cross linking polymer chains. The polymeric compatabilizing agent comprises a polyetherimide, a polyurethane, a linear segmented thermoplastic elastomer having an ester segment and a hard segment of semi-crystalline, partially aromatic polyamide based on diphenylmethane diisocyanate, hydroxyl containing phenoxypolymers, polyamide-polyarylate block copolymers, polyamide-polyester block copolymers, or blends thereof. The polycarbonate and polyamide blend may further comprise an impact modifying agent or an alloying agent.
