HEAT RESISTANT RESIN COMPOSITION, A HEAT RESISTANT FILM OR SHEET THEREOF AND A LAMINATE COMPRISING THE FILM OR THE SHEET AS A SUSBSTRATE

摘要

A heat resistant resin composition comprising 70 to 30 wt % of a crystalline polyarylketone resin having a peak melting temperature of crystal of 260 DEG 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 DEG C and 250 DEG C, determined by dynamic mechanical measurement.
