Polyester-urethanes modified with gelatine for tissue scaffolds

Abstract

Novel aliphatic PU foams, modiﬁed with gelatine, were obtained in a one-step polymerization process. Hard segments were obtained from 1,6-hexamethylene diisocyanate (HDI) and chain extenders 1,4-butanediol (BDO) or 2-(2-(2-hydroxyethoxy)ethoxy)ethanol (TG), soft segments were obtained from poly(ethylene-buthylene adipate) (EBO) polyol. We examined the PU foams for their sorption capability in canola oil, saline (0.9% NaCl water solution) and distilled water. Modi- ﬁed gelatine PUs stays stable during 24 h of incubation in canola oil. Saline and distilled water sorption decreases with time of incubation. PU-1/BDO/G20 foams, with a BDO chain extender may be used as a soft tissue scaﬀold.
