Abstract

1,174,845. Polymerization of vinyl aromatic compounds. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 21 Aug., 1968 [25 Aug., 1967], No. 39223/67. Heading C3P. In the anionic polymerization of vinyl aromatic compounds, the monomer contains in solution at least 10% by weight of a non-volatile additive which is inert to the anionic catalyst such that a major proportion of the heat of polymerization is absorbed with the reaction mixture. The additive may consist of a preformed polymer of the vinyl aromatic compound, i.e. low molecular weight polystyrene, or a lubricant and/or a toughening agent for the resulting polyvinyl aromatic compound, and may be used in an amount which is sufficient to maintain the temperature of the reaction mixture during polymerization below that at which any substantial vaporization of monomeric vinyl-aromatic compound occurs. In the example, a solution of low molecular weight polystyrene in styrene is mixed with a toluene solution of n-butyl lithium to initiate the anionic polymerization of styrene. The polymer product had a molecular weight in the range 40,000 to 100,000.
