Process for the preparation of polycondensates of amino acids and the biodegradable polypeptide hydrolysates thereof, and their use in detergent compositions |
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. |
