biodegradable polymers, process for their preparation and use for producing biodegradable moldings.

摘要

Biodegradable polyesters, which are synthesized by reacting a mixture consisting essentially of (A1) a mixture consisting essentially of 95 to 99.5% by weight of a polyester P1, which is synthesized by REACTION A MIXTURE ESSENTIALLY COMPOSITE (B1) A mixture COMPOUND A 35 to 95 mol% adipic acid or its ester-forming derivatives, or mixtures thereof, 5 to 65 mol% terephthalic acid or its ester-forming derivatives thereof or mixtures, and 0 to 5 mol% of a compound CONTAINING sULFONATE GROUPS, AND (B2) a dihydroxy compound selected from the group consisting of C {SUB alkanediols, 2} {SUB -C 6} Y {C cycloalkanediols OF SUB, SUB {5} -C, 10}, WITH CONDITION, WHICH IS USED IN COMPOUND D having at least three groups capable of ester formation for the synthesis of the polyesters P1 (A2) from 0.1 to 5% by weight of a divinyl ether C1 Y ( A3) 0 to 5 mol%, relative to component (B1) for the synthesis of P1, of compound D, AND OTHER POLYMERS AND mOLDING MASSES TERMOPLASTICAS, which are both biodegradable; PROCEDURE FOR SYNTHESIS, THEIR USE FOR PRODUCING Moldings ADHESIVES AND BIODEGRADABLE.
