1. The polymerization of 1-methyl-1,5-cyclooctadiene using metathesis catalysts proceeds with opening of the ring exclusively at the unsubstituted double bond. 2. We were the first to polymerize 3-methylcyclooctadiene and dimethyl-1,5-cyclooctadiene

1. Allyl compounds of silicon in combination with tungsten halides effectively catalyze the ring-opening polymerization of cycloolefins. 2. Polymerization of cyclopentene by the catalyst system WCl6-tetraallylsilane between -20 and -78°C forms a pol

The combination of allylsilanes and tungsten chlorides is shown to be a very effective catalyst for cyclo-olefin ring-opening polymerization. High-cis-polypentenamer was prepared between −20 and −78° by using WCl6-tetraallylsilane catalytic syst

1. A method was proposed for producing (C5H5)2TiCl2 from TiCl4 and solid C5H5Na, suspended in an inert solvent, and conditions were found under which this reaction can be directed toward the formation of C5H5TiCl3. 2. The reaction of TiCl4 with solid

The authors find that the activity of the WC1/sub 6/-PA system in the polymerization of cyclopentene (CP) may be markedly enhanced by the addition of small amounts of various oxygen-containing compounds. These additives shorten the polymerization ind
