Patent ID: 7033675

Claim:
A film of a resin composition comprising total 100 parts by weight of a crystalline polyarylketone resin (A) and a noncrystalline polyetherimide resin (B), and 5 to 50 parts by weight of a filler, said film having a peak temperature of crystallization, Tc (A+B), measured by differential scanning calorimetry at a heating rate of 10 degrees C./minute, which satisfies the following relation Tc ( A )< Tc ( A+B )≦ Tg ( B )−14.7 wherein, Tc (A) is a peak temperature of crystallization of the crystalline polyarylketone resin (A), Tc (A+B) is the peak temperature of crystallization of the film, and Tg (B) is a glass transition temperature of the noncrystalline polyetherimide resin (B), each temperature value being measured by differential scanning calorimetry at a heating rate of 10 degrees C./minute.
