Correlation Between Mechanical Properties and Degradation Processes of Poly(Methyl-Methacrylate-co-Butyl Acrylate)Films

Copolymer systems based on various molar ratio of methy methacrylate (MMA)/butyl acrylate (BA) and different mass content of N-methylolacrylamide (NMA), as a cross-linking agent, were investigated. The influence of temperature, 150 &ordm ; C, under conditions similar to those used in the textile industry, and effect of ultraviolet (UV) irradiation were examined. The changes opf mechanical properties were found to be conected with the cross-linking and/or degradation mechanisms. The effect of copolymer composition on the mechanical properties was established especially during UV degradation.
