Thermoplastic polyurethane resin composition having excellent low-temperature toughness and transparency

摘要

The present invention relates to a low-temperature impact resistance and transparency is excellent thermoplastic polyurethane resin composition , and more particularly (A) a thermoplastic polyurethane resin , and (B) MBS -based and the graft polymer in the polyurethane resin containing a thermoplastic graft polymer , the rubber used in the preparation of the latex , and the refractive index of the thermoplastic polyurethane resin by equally , provides excellent transparency and low temperature impact strength is a thermoplastic polyurethane resin composition . ; the thermoplastic resin composition according to the present invention is extremely low-temperature impact resistance without lowering the transparency of below -20 excellent .
