Compostable and thermoplastic cellulose ether-2-hydroxycarboxylic acid

Thermoplastic polyurethaneurea elastomers prepared from organic polyisocyanates (A) and a mixture (B) containing Zerewitinoff active hydrogen atoms are disclosed. The mixture (B) is prepared from 1) 40 to 85 equivalent-% (relative to isocyanate groups in (A)) of one or more compounds having an average of at least 1.8 Zerewitinoff active hydrogen atoms and a number average molecular weight of 400 to 10,000, 2) 10 to 60 equivalent-% (relative to isocyanate groups in (A)) of water and 3) 0 to 45 equivalent-% (relative to isocyanate groups in (A)) of one or more chain extenders having an average of at least 1.8 Zerewitinoff active hydrogen atoms and a molecular weight of 62 to 400. The preparation process comprise mixing (A) and (B) in a static mixer under conditions in which no reaction occurs between (A) and (B), and reacting the mixture in a second static mixer. The resulting polyurethaneurea elastomer is useful for the production of moldings.
