Abstract
Polyester resin compositions include a crystalline thermoplastic polyester resin (such as polybutylene terephthalate), a polyester elastomer (such as a copolymer including recurring hard and soft segments) and between 0.005 to 10 parts by weight, based on 100 parts of the crystalline and elastomeric resins, of an amide compound having the formula (I) ##STR1## wherein R is an organic group such as an aromatic ring, X is an alkylene of C.sub.2 to C.sub.10 such as ethylene and propylene, Y is --COOH, --OH, --SH or --NH.sub.2 and n is 2 to 4, inclusive.
