Synthesis and preliminary photocrosslinking studies of new photocurable poly(ester-urethane)s for biomedical applications

Skrobot J., EL Fray M.

Polish Journal of Applied Chemistry

2009

Vol. 53, nr 2

175-180

New segmented photocurable poly(ester-urethane)s were synthesized in bulk. First, the soft segment composed of the unsaturatcd dicarboxylic fumaric acid and a renewable dimer fatty acid diol was synthesized, thus giving the ester block. The hard urethane segments were built up of aliphatic diisocyanate and different chain extenders, namely 1,4-butanediol (BD) or glycerol (GLY). The photoinitiator was introduced by solution mixing and subsequent solvent casting and light-curable films were obtained. The structure of the materials was analyzed. The FT-IR and DSC studies were performed to verify the material chcmical and phase structure.
