Síntesis y polimerización de bis-macromonómeros de poli(E-caprolactona)

Abstract

Poly(e-caprolactone) (PCL) bis -macromonomer was obtained by the esterification reaction of poly(e-caprolactone) diol with acryloyl chloride. The functionalization of the end-groups of the polymer chains was in the order of 40 % as determinate by proton nuclear magnetic resonance ( 1 H-NMR). Then, PCL networks synthesis was performed and theirs thermal behavior, swelling degree and hydrophilic and hydrophobic interactions were analyzed. The network swelling degree is depended on the degree of polymerization of the bis-macromonomer. The PCL networks swelled considerably in slightly polar and non-polar solvents.
