Abstract
The invention is directed to biomedical polyurethanes. The invention is particularly directed to biomedical polyurethanes with improved biodegradability and to an improved preparation of the biomedical polyurethanes. In particular the present invention provides a biomedical polyurethane having the formula (A-B-C-B)n, wherein A denotes a polyol, B denotes a diisocyanate moiety, C denotes a diol component and n denotes the number of recurring units, and wherein the B-C-B segment is bioresorbable.
Claims10
Biomedical polyurethane having the formula A-B-C-Bn, wherein A denotes a polyol comprising a prepolymer that is at least partially based on a random copolyester, wherein the polyol is a soft segment, B denotes 1,4-butane diisocyanate, C denotes 1,8-octanediol and n denotes the number of recurring units, wherein the B-C-B segment is bioresorbable.
