Abstract

Block polymers are produced by polymerizing a polyunsaturated compound containing an ethylenic double bond in conjunction with a second centre of unsaturation represented by the formula: <FORM:0852823/IV(a)/1> in the presence of an active hydrocarbon polymer produced by anionic polymerization of a polyunsaturated hydrocarbon containing an ethylenic double bond in conjugation with a second centre of unsaturation represented by the formula: <FORM:0852823/IV(a)/2> under substantially anhydrous conditions in the absence of oxygen, the polymerizable compound being different from that used in the last previous polymerization step in the production of the active polymer. Polyunsaturated compounds specified are styrene, alpha-methyl styrene, butadiene, isoprene, 2, 3-dimethyl butadiene, pentadiene-1, 3, cyclopentadiene, methyl acrylate and methacrylate, acryonitrile and methacrylonitrile. In the anionic polymerization step there may be used the unsaturated hydrocarbons specified above. The anionmic polymerization may be effected by contacting the unsaturated hydrocarbon with the addition compound of an alkali metal with a polycyclic aromatic compound e.g. naphthalene, anthracene or phenanthrene, the reaction preferably being carried out in a solvent such as tetrahydrofurane, dioxane and dimethyl and diethyl glycol ethers. The block polymerization reaction occurs when the polyunsaturated compound is added to the anionically polymerized unsaturated hydrocarbon, and when the added compound is itself a hydrocarbon the resulting block polymer is capable of functioning as a promoter for the polymerization of a further polyunsaturated compound. The following block polymers are described in the examples: (1) polystyrene-polymethyl methacrylate; (2) polyisoprene-polystyrene; (3) polystyrene-polyisoprene; and (4) polybutadiene-polystyrenepolyisoprene.
