POLYARYLETHER-POLYETHERIMIDE COMPOSITIONS

摘要

A heat resistant resin composition comprising 70 to 30 wt % of a crystalline polyarylketone resin having a peak crystalline melting temperature of 260° C. or higher and 30 to 70 wt % of a noncrystalline polyetherimide resin, wherein said composition has at least 2 peaks of loss tangent (tan delta) between 140° C. and 250° C., determined by dynamic mechanical measurement.
