The invention provides a heat-resistant modifier ACR for PVC sheets, and relates to the technical field of modifier production. The PVC sheet heat-resistant modifier ACR includes the following materials, and each weight portion of raw materials is weighed according to the following formula: 35 parts of styrene, 47 parts of acrylonitrile, 40 parts of methacrylates, α-methyl styrene 20 parts, 30 parts of glycidyl methacrylate, by copolymerizing styrene, acrylonitrile, methacrylates, α-methylstyrene and glycidyl methacrylate to obtain PVC sheet heat-resistant modifier ACR , styrene, acrylonitrile, methacrylates, α-methylstyrene and glycidyl methacrylate copolymerization reaction equipment is a leak-proof reaction equipment. The invention can make the modifier ACR of the PVC sheet have good heat resistance, and the reaction equipment is safer during the polymerization reaction, and the leakage of flammable and harmful substances will not be caused. |
