Abstract
1,252,799. Cyclic polymers. B.P. CHEMICALS Ltd. 21 April, 1970 [17 June, 1969], No. 30573/69. Heading C5E. [Also in Division C3] Cyclic polymers of formula are produced from one or more cyclic olefins of formula in which R and R<SP>1</SP> are hydrogen atoms or alkyl, aryl, alkaryl or cycloalkyl groups, n is a positive integer of 5-18 which may be different in each monomer if the feed is a mixture, and x is the degree of polymerization, by polymerization in the presence of a disproportionation catalyst comprising (1) a salt of molybdenum or tungsten, and (2) an organometallic compound of a Group IV B metal (Mendeleef), at a temperature in the range - 100‹ C. to + 300‹ C. and a pressure in the range 10 mm. of Hg to 2000 p.s.i.g. The Mo or W salts may contain triphenyl phosphine or carbon monoxide ligands, and are preferably WCl 6 or MoCl 5 . The Group IV B compound is preferably tetra(n-butyl)tin. In the example cyclo-octene is polymerized to a product of unspecified M.W. The feeds for the above process are suitably purified by treatment with WCl 6 followed by removal thereof by percolation through a silica column.
