Modification of hydrolytic stability of high molecular weight poly(e-caprolactone) by addition of medium molecular weight poly(e-caprolactone) agregated in the presence of CaO (in English)

Summary

Medium molecular weight poly(e-caprolactone) containing three carboxyl groups at one chain end (PCL5000) and the same polymer but aggregated in the presence of CaO (PCL5000/CaO) were used as an additive for modification of hydrolytic stability of high molecular weight poly(e-caprolactone) (PCL80000). Thermal and mechanical properties of PCL80000 and its composites together with their molecular weight changes upon hydrolysis were investigated. The composite obtained using PCL5000/CaO showed higher tendency to hydrolytic degradation than unmodified PCL80000 with the preservation of mechanical properties.


Key words: biodegradable polyester, poly(e-caprolactone) modification, composites, hydrolytic degradation
