Abstract

1406464 Allyl uranium compounds in diolefin polymerization SNAM PROGETTI SpA 21 Nov 1972 [26 Nov 1971] 8596/75 Divided out of 1406461 Addition to 1246424 Heading C3P Conjugated diolefins and monolefins are homo- or copolymerized in the presence of allyl uranium compounds of the formula wherein each of the R's is hydrogen or a C 1-10 hydrocarbyl group. A Lewis acid cocatalyst may also be present In examples butadiene and isoprene are homopolymerized using (pi-allyl) 4 U together with AlEtCl 2 , BCl 3 or TiCl 4 , in hexane.
