Injection moldable polyamide imide from trimellitic anhydride end capped
with aniline
摘要:
Novel polymers and molding compositions are prepared from acyl halide derivatives of tricarboxylic acids and diamines and about 1 to about 10 percent by weight of phthalic anhydride, trimellitic anhydride or aniline moieties. The polymers are useful in engineering plastics.
