Abstract
PURPOSE: To provide titled molded article in which appearance and extrusion moldability are improved, by a method wherein a polybutylene terephthalate is pre- kneaded with a polyether ester block copolymer, and the resulting product is extrusion-molded.
CONSTITUTION: (B) 1W10pts.wt. of a polybutylene terephthalate derived from terephthalic acid and 1,4-butanediol is pre-kneaded with (A) 100pts.wt. of a polyether ester block copolymer derived from terephthalic acid, 1,4-butanediol, a dicarboxylic acid other than terephthalic acid and/or a low-molecular diol other than 1,4-butanediol and a poly(alkylene oxide)glycol having a number-average MW of 300W6,000. By this pre-kneading, the component B is finely dispersed in the component A. Then the component A is molten at a temp. of not higher than 215°C, and the pre-kneaded material is extrusion-molded at a temp. at which the component B is present as a solid phase, to obtain the desired molded article.
