| titleOfInvention | A kind of methyl methacrylate polymer and its preparation method and application |
| abstract | The invention relates to the technical field of waterproof coatings, in particular to a methyl methacrylate polymer and its preparation method and application. Among them, the methyl methacrylate polymer is mainly formed by polymerizing methyl methacrylate as a monomer; it contains carbon-carbon unsaturated groups. The preparation method is that methyl methacrylate, glycidyl methacrylate or glycidyl acrylate and azobisisobutyronitrile are polymerized at 40°C~60°C for 0.5~1h to obtain epoxy side group-containing The methyl methacrylate prepolymer; add 500~1000ppm of polymerization inhibitor and acrylic monomer to the methyl methacrylate prepolymer, and react at 100~120°C for 1~3h to obtain the methyl methacrylate ester polymer. The invention solves the problem that the methyl methacrylate prepolymer cannot be stably fused with the active diluent as a film former by introducing carbon-carbon unsaturated groups, and has high stability and mechanical properties. |
