Abstract
The biodegradation of blends of polycaprolactone PCL and polyvinyl chloride PVC has been studied Blends of composition PCL/PVC 11 and 12 w/w were tested The 11 blend contained crystals in the ascast state and became more crystalline on exposure to different bioactive agents The 12 blend was amorphous in the ascast state but developed a significant crystal component after 4 months exposure to the bioagents Three bioactive agents were used and all were found to produce qualitatively similar behaviour but their activity was somewhat different For both the 11 blend and the 12 blend the ranking of the three bioactive agents tested in increasing order was Curvularia sp Trogia buccinalis Phanerochaete chrysosporiumSMMF thanks FAPESP Brazil for a postdoctoral scholarship 03/022560 that enabled her to make an extended visit to Newcastle to facilitate collaboration with the UK authors The authors thank Instituto Botânico São Paulo Brazil for supplying the fungi Trogia buccinalis and Phanerochaete chrysosporium from its Culture Collection CCB and Dr José A M Agnelli DEMAUFSCar SCarlos SP Brazil for supplying PCL
