The Polarity of poly(methyl methacrylate) Copolymers

Poly (methyl methacrylate) (PMMA) is known as one of the common transparent polymer materials. In this work, pure poly (methyl methacrylate), methyl methacrylate-acrylonitrile copolymer, methyl methacrylate-styrene copolymer was synthesized by bulk polymerization based on the mechanism of free radical polymerization to observe the polarity change of the PMMA after introducing styrene and acrylonitrile monomers. Meanwhile the glass transition temperature, hardness, contact angle and color distribution of the copolymer were measured through polymer temperature deformation analysis experiment, hardness and contact angle measuring instrument.
