organic synthesis intermediates, is also a monomer for the synthesis of high molecular polymers. The rubber copolymerized with methyl acrylate has good resistance to high temperature and oil. Copolymerization with acrylonitrile can improve its spinnability, thermoplasticity and dyeing properties. With methyl methacrylate vinyl acetate or styrene copolymerization, can produce good performance of coatings and floor polish. It is also widely used in pharmaceutical manufacturing, leather processing, paper making and adhesive manufacturing.
