Abstract

1310621 Syndiotactic 1,2-polybutadiene UBE INDUSTRIES Ltd 1 Dec 1970 [2 Dec 1969 (2)] 57056/70 Heading C3P Butadiene is polymerized to 1,2-polybutadiene in the liquid monomer or in an inert liquid diluent by using a catalyst comprising (a) a cobalt compound, (b) an organoaluminium compound, AlR 3 , where R is a C 1 -C 6 hydrocarbon group, (c) carbon disulphide and optionally (d) a nitrile R1(CN) n where n is 1 or 2 and R1 is a mono- or di-valent aliphatic, araliphatic or aromatic hydrocarbon group. When only components (a), (b) and (c) are used a novel polymer is obtained having a linear, highly syndiotactic structure, a melting point of at least 200‹ C. and good solvent resistance. Addition of component (d) in varying amounts enables polymers to be produced with a selected melting point in the range 100-210‹ C. The catalyst components are preferably mixed in the presence of the butadiene. The cobalt compound should preferably be soluble in the reaction medium, e.g. with benzene as the diluent, cobalt octoate, naphthenate or acetylacetonate or CoCl 2 complexes, such as the pyridine complex. As component (b), Et 3 Al is exemplified and as component (d), acetonitrile, benzonitrile, adiponitrile, sebaconitrile or benzyl cyanide.
