Abstract

1,170,589. Stereospecific polymerization catalysts for dienes. INSTITUT FRANCAIS DU PETROLE DES CARBURANTS ET LUBRIFIANTS. 20 Dec., 1966 [22 Dec., 1965], No. 56988/66. Heading C3P. A catalyst for the stereospecific polymerization of conjugated dienes contains an organomagnesium compound, cobalt difluoride, and an orthophosphortriamide or a pyrophosphortetramide in which all the hydrogen atoms attached to all the nitrogen atoms are substituted. Specified phosphoramides are hexamethyl-, hexaethyl-, hexaoctyl-, diphenyltetramethyl-, and cyclohexylpentamethyl-phosphortriamide, pyrrolidinotetramethylphosphordiamide, dipiperidinodiethylphosphoramide, and octamethylpyrophosphoramide. The organomagnesium compound of which a list is given correspond to the general formula R 2 M g , or RMgX where R is a monovalent hydrocarbon radical, and X is a halogen. When the catalysts are used for polymerizing one or more dienes, or one or more dienes with other ethylenically unsaturated compounds, the phosphoramide if liquid, may be employed as the solvent, or a hydrocarbon solvent may be used. Specified dienes are butadiene, isoprene and piperylene. The polymers are recovered by conventional techniques. The monomeric units in the polymer have mainly a 1,2-structure. The polymers prior to recovery may be stabilized with betaphenylnaphthylamine or p-tert-butylcresol. The polymerization is preferably carried out between - 20‹ and 40‹ C. All the examples used temperatures of - 20‹ C.
