    摘要： A process for the production of thermoplastic polyurethane elastomer is disclosed. The process entails (a) introducing and homogeneously mixing in a first static mixer (A) an isocyanate and (B) a mixture of compounds having an average of 1.8 to 3.0 Zerewitinoff active hydrogen atoms having a molecular weight of 400 to 10000 with and chain extenders having an average of 1.8 to 3.0 Zerewitinoff active hydrogen atoms and a molecular weight of 62 to 400 and optional auxiliaries to form a substantially unreacted mixture and (b) reacting said substantially unreacted mixture in a second static mixer to form thermoplastic polyurethane elastomer. The elastomer thus produced has improved mechanical properties and is suitable for the production of moldings.
