Description
Copolymerized with vinyl chloride, ethylene, acrylonitrile, etc. to produce various copolymers, which can be used to make films, floors, film pressed products, adhesives and coatings; copolymers with crotonic acid can be used to make film-forming agents and tackifiers Agents, sizing agents, protective films, etc.; copolymers with maleic acid (anhydride) are used to manufacture efficient water quality stabilizers, anti-scaling agents, etc.
