<p>A compatibilizing agent for polymeric blends of polycarbonates and polyamides which have improved physical and chemical resistance properties, without any substantial sacrifice of the desirable properties of the polycarbonate or polyamide. The polymeric compatibilizing agent has at least one functional group soluble in the polycarbonate and at least one functional group soluble in the polyamide with a melting or softening point of said compatibilizing agent is no greater than the melting or softening points of the polycarbonate and polyamide resin constituents in the blend, and preferably is a polyetherimide, polyurethane and linear segmented thermoplastic elastomer having an ester segment and a hard segment of semi-crystalline, partially aromatic polyamide, based on diphenylmethane diisocyanate; and, optionally, an impact modifying agent, preferably of a maleic anhydride grafted polymeric blend, and/or an alloying agent. A process for producing these polycarbonate/polyamide polymeric blends is provided.</p> |
