POLYOXYMETHYLENE RESIN COMPOSITIONS HAVING ENHANCED TENSILE ELONGATION, THERMAL STABILITY AND IMPACT RESISTANCE

摘要

A polyoxymethylene resin composition, having enhanced tensile elongation,thermal stability, processibility and impact resistance,comprises: (i) from 50 to less than 97 % by weight of a polyoxymethyleneresin; (ii) from 3 to less than 50 % by weight of an elastomerhaving a thermoplastic polyester elastomer and optionally a thermoplasticpolyurethane elastomer; and (iii) from 0.1 to less than 10 % byweight of a maleic anhydride-grafted polymer, based on the total weight of(i), (ii) and (iii).
