VERFAHREN DER HERSTELLUNG VON AMINOSÄURE- POLYKONDENSATEN UND DEREN BIOABBAUBARER POLYPEPTID-HYDROLYSATE, IHRE VERWENDUNG IN DETERGENS-ZUSAMMENSETZUNGEN

摘要

Prodn. of amino acid polycondensates or their polypeptide hydrolysates comprises subjecting an homogeneous powdered mixt. of amino acid and catalyst to thermal polycondensation and opt. hydrolysing the prod. The catalyst is H3PO4, P2O5 or polyphosphoric acid (PPA). The molar ratio of catalyst to amino acid is 0.005-0.25:1, pref. 0.01-0.18:1.
