Abstract

Polymethylmethacrylate (PMMA)/Polyvinylchloride (PVC) blends were prepared using a solvent casting technique. The blends were characterized using  Fourier Transform Infrared Spectroscopy (FT–IR), Scanning Electron Microscopy (SEM) and biodegradation. The liquid absorption behaviours as well as the  optical parameters of the prepared blends were investigated using UV- Visible spectroscopy. Optimum liquid absorption was observed in the blend  that contained75% PMMA and 25% PVC, with the liquid absorption increasing from 65.09% in first day to 145% in the third day. The absorption  coefficients (α) and extinction coefficient (k) of the various compositions were determined and the highest α value was observed in 50% PMMA/50% PVC  blends of 3166.63α and 88.4k.
