(1) Copolymer of methyl methacrylate and styrene: 372 resin, mainly methyl methacrylate monomer. When the content of styrene monomer is small, the performance of the copolymer is closer to PMMA and purer than PMMA. There is some improvement in performance, called styrene-modified polymethyl methacrylate. When the above structural formula is increased by x:y=15:85, the obtained copolymer is brand No. 372 resin, which is modified organic glass molding. One of the main varieties of plastics maintains the mechanical properties and weatherability of PMMA, the molding fluidity is improved, and the hygroscopicity is reduced.
(2) Methyl methacrylate, styrene, nitrile rubber copolymer: 100 parts of 372 resin and 5 parts of nitrile rubber are blended, and the obtained blend material is called 373 resin, and its impact toughness can be multiplied. It is also one of the main varieties of molding materials for modified plexiglass.
(3) Methyl methacrylate and styrene, butadiene rubber copolymer: a graft copolymer of methyl methacrylate and styrene grafted on the macromolecular chain of butadiene rubber. It has high gloss, high transparency and high toughness, good dyeability, high light transmittance and UV resistance, and can be used as a transparent material or as an impact modifier.
