Polycaprolactone, a semi-crystalline linear resorbable aliphatic polyester, is subjected to biodegradation, because of the susceptibility of its aliphatic ester linkage to hydrolysis. In this research, polycaprolactone diacrylate was synthesized by reaction of polycaprolactone diol withacryloyl chloride. The macromer was characterized using spectroscopic and chromatographic techniques. PCLA macromer was photo-crosslinked using methacryl-POSS cage mixture. Double bonds conversion of PCLA during photo-crosslinking was followed using FT-IR and shrinkage strain studies.
