摘要:
In a process for recovering a rubberlike copolymer from a hydrocarbon or halogenated hydrocarbon solution containing the copolymer, the solution being obtained by copolymerizing ethylene and an a-olefin represented by the general formula CH 2 = CHR, wherein R is a linear or a branched alkyl group of 1 to 6 carbon atoms, or by copolymerizing these and a non-conjugated linear or cyclic diene, in the presence of a catalyst containing an organoaluminum compound and a vanadium compound, the improvement which compriese dispersing the rubber like copolymer solution in hot water in the presence of a block type polyether compound represented by the general formula HO(C 2 H 4 O) a (C 3 H 6 O) b (C 2 H 4 O) c H, wherein a, b and c independently represent numbers of 10 to 1000, to strip the solution and separating the resulting granular copolymer from water to recover it in a granular form.
