Investigation of effects of reactive copolymer containing maleic anhydride on thermomechanical properties of ternary blends of poly(methyl metacrylate) (PMMA)

Abstract

In the present paper, the effects of reactive copolymer containing maleic anhydride on the thermomechanical properties of poly(methyl metacrylate) (PMMA) were investigated. Maleic anhydride–styrene (MA–St) and aniline maleamidic acid–styrene copolymers (AnMAA–St) were used as reactive copolymers. Multicomponent blends such as PMMA/MA–St/AnMAA–St were prepared and thermomechanical characterisation of these blends was performed by thermomechanical analysis method (TMA). The blends were prepared by changes of the weight ratios of MA–St and AnMAA–St copolymers in the blends. PMMA contents in all the blends are fixed at a weight of 75%. Consequently, it is clear that MA–St copolymer can be used for changes of the thermomechanical properties of PMMA.
