| titleOfInvention | Preparation method of graft copolymer with excellent impact strength |
| abstract | The invention belongs to the technical field of macromolecular materials, relates to a method for preparing a copolymer of butadiene copolymer latex grafted with vinyl chloride monomer, and particularly relates to a method for preparing a graft copolymer with excellent impact resistance, which improves the graft polymerization system. stability and improve the impact strength of the copolymer. The preparation method includes butadiene latex preparation, latex diameter expansion, and vinyl chloride graft copolymerization. The preparation method of the present invention uses C12-C18 fatty acid soluble alkaline salts as emulsifiers to prepare butadiene copolymer latex, and then increases the particle size of latex particles through a diameter expander, thereby preparing vinyl chloride graft copolymerization with excellent impact resistance performance Process of resin. |
