| titleOfInvention | Preparation method of comb-shaped vinyl polyolefin thermoplastic elastomer |
| abstract | The invention discloses a comb-shaped vinyl polyolefin thermoplastic elastomer and a preparation method thereof, the comb-shaped vinyl polyolefin thermoplastic elastomer takes a crystallized polyethylene hard segment as a side chain and an amorphous ethylene/alpha-olefin copolymer soft segment as a main chain, and a first reactor is used for synthesizing a crystallized polyethylene macromonomer through a cascade catalysis system in a high-temperature high-pressure solution polymerization system, and the ternary polymerization of ethylene, alpha-olefin and the polyethylene macromonomer is carried out in a second reactor to synthesize the comb-shaped vinyl polyolefin thermoplastic elastomer. The comb-shaped vinyl polyolefin thermoplastic elastomer prepared by the invention can be used for replacing the application field of the traditional polyolefin thermoplastic elastomer and has high industrial value. |
