Abstract: A process for the preparation of trans-polyalkenamers by the polymerisation of cycloolefines in solutions of hydrocarbons with the aid of organometallic mixed catalysts of tungsten compounds, organo aluminium compounds and optionally co-catalysts, wherein polymerisation is carried out in the presence of hydrogen chloride, the molar ratio of hydrogen chloride to tungsten being from 0.1:1 and 10:1.

Abstract: A PROCESS FOR ISOLATING POLYISOPRENE FROM A CATALYSTCONTAINING SOLUTION THEREOF IN AN ORGANIC SOLVENT, WHEREIN (1) THE CATALYST IS DEACTIVATED IN THE POLYMER SOLUTION WITH AN AQUEOUS OR ALCOHOLIC SOLUTION OF A HYDROXIDE OF A METAL OF GROUPS 1A OR 2A OF THE PERIODIC SYSTEM; (2) THE DEACTIVATED SOLUTION IS WASHED WITH WATER, STABILISERS AND/OR MODIFIERS OPTIONALLY BEING ADDED IN STAGE 1 OR STAGE 2; (3) THE AQUEOUS OR AQUEOUS/ALCOHOLIC PHASE IS SEPARATED OFF; (4) AN ALIPHATIC DIAMINE OR POLYAMINE IS ADDED, AND (5) THE ORGANIC SOLVENT IS REMOVED BY STREAM DISTILLATION.
