PURPOSE:To provide the title resin having excellent crystallizability, moldability and productivity, by adding polytetramethyleneadipamide to polyethylene terephthalate. CONSTITUTION:Polyethylene terephthalate (A) obtd. by copolymerizing terephthalic acid component, ethylene glycol and optionally, an acid component, a glycol ether component, etc., is molten. 0.02-10wt% polytetramethylene adipamide obtd. from 1,4-diaminobutane and adipic acid and optionally, other polymer (e.g. polybutylene terephthalate), nucleating agent (e.g. talc), low- molecular plasticizer (e.g. alkylbenzenesultoneamide), bundling agent, thermal stabilizer, etc., are then added thereto. |
