PCT No. PCT/NL95/00140 Sec. 371 Date Dec. 26, 1996 Sec. 102(e) Date Dec. 26, 1996 PCT Filed Apr. 18, 1995 PCT Pub. No. WO95/30698 PCT Pub. Date Nov. 16, 1995The invention relates to a process for the preparation of a polymer from ethylene, an alpha -olefine and optionally a diene, according to which these monomers are polymerized under the influence of a metallocene catalyst, the polymerization taking place in the presence of a catalyst comprising a specific 2-indenyl metallocene, resulting in a bimodal, elastomeric polymer with a molecular weight distribution of more than 3.5, under such reaction conditions that the amount of water in the polymerization medium is smaller than 0.5 ppm. The invention also relates to polymers with a specific branching index.
