Ethylene → Ethylene styrene

Participants

Reaction Steps

After the completion of the polymerization, 250 ml of isobutyl alcohol and 10 ml of aqueous hydrochloric acid were added to the mixture and heated at 80° C. for 30 min under agitation. The obtained reaction mixture containing isobutyl alcohol was transferred to a separating funnel, washed with 250 ml of water twice and separated into an oil phase and a water phase. The oil phase was poured into 3 lit. of methanol to thereby precipitate a polymer. The precipitated and separated polymer was dried in vacuum at 130° C. for 12 hr, thereby obtaining 20 g of a polymer having an ethylene content of 86.5 mol % and a styrene content of 13.5 mol % (copolymer (d)). This copolymer (d) exhibited an intrinsic viscosity [η] of 1.1 dl/g which was measured in 135° C. decalin and a melting point (Tm) of 53° C. which was measured by a differential scanning calorimeter.
