Abstract: A catalyst comprising (1) an allyl compound of Cr, W, Mo, or Zr and (2) a halide, oxyhalide, ester halide, or ester of one or more elements of subgroups IVA to VIIA and Group VIII of the Periodic Table is used for the homo- and copolymerization of olefinically unsaturated compounds. Specified components (1) are:-chromium trisallyl, diallyl chromium chloride, dially chromium iodide, zirconium tetraallyl, di(bisallyl molybdenum), and tetraallyl molybdenum or tungsten. Suitable components (2) are the halides, oxyhalides, ester-halides and esters of Ti, Zr, V, Cr, Mo, W, Fe, U, Th. Exemplified monomers are:-ethylene, propylene, pentene-(1), 4-methyl-pentene-(1), styrene, 1,3-butadiene, dicyclopentadiene, and 5-(2-butenyl) -2-norbornene.ALSO:A tetra-allyl zirconium solution (see Example 32) is prepared by (1) suspending zirconium tetrachloride in absolute ether, (2) suspending allyl magnesium chloride in ether, (3) dropping the suspension from (1) into the suspension from (2) at 0 DEG C., with stirring, and over a period of three hours, (4) allowing the mixture to stand for ten hours, (5) separating the dark red solution from the precipitated magnesium chloride by filtration, (6) removing the ether of the solution under reduced pressure, and (7) taking up the residue in hexane. Trisallyl chromium and tetraallyl molybdenum are also disclosed.
