| abstract |
The invention relates to a process for the suspension polymerization of conjugated dienes, in hydrocarbon mixtures with more than 80% by volume of C 4 hydrocarbons, characterized in that in the presence of a compound of rare earths, one or more aluminum compounds and optionally another Lewis acid polymerizes, the polymers that can be produced according to the invention, and their use for the production of moldings of all kinds, in particular tires, technical rubber goods and for mixing with polystyrene (HIPS). |
