Abstract
PURPOSE: To prepare a modified polybutylene terephthalate suitable for injection molding, extrusion molding and blow molding, and having excellent elasticity, flexibility, melt flowability, etc.,by melt blending the polyester with specific diisocyanate.
CONSTITUTION: (1) 100 Parts by weight of polybutyline terephthalate is melt mixed with (2) preferably 0.5W10 parts by weight of a polyether diisocyanate and/or a polyester diisocyanate having a molecular weight of 800W5,000 to give the desired modified polyester. The diisocyanates are prepared by reacting a polyether, e.g. polyethylene glycol having a molecular weight of 500W2,000, etc., or a polyester, e.g. poly-ε-caprolactone, etc., with a diisocyanate (e.g. hexamethylene diisocyanate, etc.)
