Ethylene → ethylene MMA

Participants

Reaction Steps

2 ml of purified methylmethacrylate (MMA) was charged in the above flask where ethylene polymerization had been conducted, and block copolymerization was initiated at room temperature. After 2 hours, the reaction solution was poured into a large amount of methanol to stop polymerization and to precipitate a polymer. The polymer thus precipitated was filtrated, washed with methanol and dried under reduced pressure to measure its weight. The polymer thus obtained was extracted with chloroform in a Soxhlet apparatus for 4 hours, and the part insoluble in chloroform was taken out and dried to measure its weight. In this manner, 710 mg of white fine powdery ethylene/MMA block copolymer was obtained.
