Abstract

PURPOSE:To obtain titled composition of high heat distortion temperature under heavy load, with low water absorptivity and small drop in its heat distortion temperature despite water absorption, by blending a maleimide copolymer with polybutylene terephthalate. CONSTITUTION:The objective composition can be obtained by blending (A) 5-95 (pref. 50-95)pts.wt. of a maleimide copolymer with (B) 95-5 (pref. 50- 5)pts.wt. of polybutylene terephthalate. The content of the maleimide monomer in the component (A) will be 10-90 (pref. 30-70)wt%. A product formed by imide ring closure with ammonia, etc., of a copolymer containing or not containing a rubbery polymer prepared by copolymerization of maleic acid (anhydride) would be effectively used as an example of the component (A).

Published in 1979]. However, maleimide copolymers have a large water absorption property, and have the disadvantage that they absorb water in a high humidity atmosphere or when immersed in water, resulting in a decrease in heat distortion temperature, and there is a desire to improve their water absorption properties.
