Abstract
A polyester resinous composition comprising (a) an aromatic polyester, (b) a copolymer of an .alpha.-olefin and a glycidyl ester of .alpha.,.beta.-ethylenically unsaturated carboxylic acid and (c) an ethylene based copolymer of ethylene and .alpha.-olefin having more than three carbon atoms. The composition has highly improved impact strength at low temperature and good flow properties upon injection molding. The composition can be molded to form various articles by conventional molding methods.
