Irradiation of benzophenone (BP)-doped poly(epsilon-caprolactone) (PCL) films at lambda > 350 nm alters the molecular characteristics, viscoelastic properties and hydrolytic degradation rate. The influence of BP concentration on changes caused by irradiation of BP-doped PCL film was investigated using gel permeation chromatography along with analyses of gel content, DSC and rheology. Changes in the rate of basic hydrolysis of irradiated BP-doped PCL films were also investigated. Irradiation of PCL film doped with at least 0.5% w/w BP led to cross-linking and gel formation, even though simultaneous degradation was also observed. Polar groups formed during the irradiation of BP-doped PCL films enhanced the hydrolysis of cross-linked PCL films compared with untreated films. (C) 2015 Elsevier Ltd. All rights reserved.
