Thermoplastic polyoxymethylene molding composition of high toughness and its use |
摘要 |
Thermoplastic molding composition composed of A) 50 to 95% by weight of polyoxymethylene, B) 5 to 50% by weight of a rubber-elastic graft copolymer and optionally customary additives, in which the component B) is composed of a rubber-elastic core based on at least one polydiene, which is at least partially crosslinked, and at least one hard graft shell and has a bimodal particle size distribution. Monomers for formation of the graft shell are styrene, (meth)acrylonitrile and/or methyl methacrylate. The moldings produced from the molding compositions possess good tough fracture characteristics even at low temperatures.
