A thermoplastic polyester composition comprises polyalkylene terephthalate, a block copolymer comprising a semi-crystalline polyolefin block and at least one of a vinyl aromatic polymer block and an elastomeric polyolefin block, and reinforcing filler. The composition is capable of providing insert-molded articles, comprising a metal part, with high durability and resistance to cracking when subjected to a rigorous thermal cycle. |
