Uses: 1. This product is a polymerization regulator for synthetic rubber, synthetic resin, and synthetic fiber. It is especially commonly used in the manufacture of styrene butadiene rubber and ABS resin. It can reduce the degree of branching of polymer chains and make molecular weight distribution uniform. It is often used as Non-ionic surfactants and organic synthesis intermediates. Used to make fungicides, insecticides, rust inhibitors, lubricant additives, medicines, etc. It can also be used as "gold water" and oil well acidifier in ceramic industry. It is also used as a stabilizer and antioxidant for the production of polyvinyl chloride, polyethylene and polypropylene. 2. It is a relative molecular mass regulator for the polymerization of synthetic rubber, synthetic resin and synthetic fiber, especially widely used in the synthesis of adhesives, styrene butadiene rubber and ABS resin produced by emulsion polymerization, which can reduce the branching of polymer molecular chains. The degree of chemical conversion, and make the relative molecular mass distribution uniform. It is also used as a non-ionic surfactant and organic synthesis intermediate, used to manufacture drugs, insecticides, fungicides, rust inhibitors, lubricant additives, oil well acidifiers, etc. It can also be used as "gold water" in the ceramic industry. It can also be used as a stabilizer and antioxidant for the production of polyethylene, polypropylene, and polyvinyl chloride.
