IMPACT MODIFIED POLYURETHANE-POLYESTER MOULDING THERMOPLASTICS, PROCESS FOR THEIR PREPARATION AND THEIR USE

摘要

The invention relates to impact-modified thermoplastic polyurethane/polyester moulding materials which contain, based on 100 parts by weight of (A) to (C), … …  A) 30 to 90 parts by weight of at least one thermoplastic polyurethane elastomer, …  B) 5 to 65 parts by weight of at least one thermoplastic polyester, preferably a polyalkylene terephthalate, and …  C) 5 to 30 parts by weight of at least one graft rubber based on a polybutadiene (C1) or polyacrylate (C2) or a mixture of these graft rubbers and …  D) 0 to 60% by weight of at least one fibrous and/or particulate filler and …  E) 0 to 10% by weight of at least one auxiliary, the percentages by weight being based on the weight of (A) to (C), … a process for their preparation by homogenisation of the components at a temperature in the range from 190 to 250 DEG C, and their use for the production of mouldings.
