Effect of Copper Phthalocyanine Derivative on the Mechanical Property of Poly (methyl methacrylate)

Abstract

The interaction between copper phthalocyanine (CuPC) and poly (methyl methacrylate) (PMMA)was investigated. Th e differrence spectrum between 10^-5 mol dm^-3 CuPC + 0.01 mol dm^-3PMMA acetone solution and 10^-5 mol dm^-3CuPC acetone solution showed a mini. at 625 nm and a maximum at 640 nm and the existence of the relatively strong interaction between CuPC and PMMA were recognized. The dynamic modulus of PMMA including 1 mol% CuPC was 2.5 times greater than that of pure PMMA. It was shown by employing SAICAS method that cutting strength of PMMA including 1 mol% CuPC was lower than that of pure PMMA. Comparison of the thermal gravitation curve of pure PMMA with that of PMMA including CuPC indicated that heat resistance of PMMA including CuPC was higher than that of pure PMMA.
