| titleOfInvention | METHOD FOR POLYMERIZATION IN MASS FOR PRODUCING POLYDIENES |
| abstract | 1. A method of producing polydiene, comprising the steps of: polymerizing a conjugated diene monomer using a catalytic system containing a metallocene complex, in a polymerization mixture containing less than 20% solvent of the total weight of the polymerization mixture, where the catalytic system containing a metallocene complex includes a combination or a reaction product : (a) a metallocene complex, (b) an alkylating agent, and possibly (c) a non-coordinating anion. 2. A method according to claim 1, characterized in that the polymerization mixture comprises less than 5% solvent of the total weight of the polymerization mixture. A method according to claim 1, characterized in that said polymerization step is carried out in a polymerization mixture essentially free of solvent. The method according to any one of paragraphs. 1-3, characterized in that the metallocene complex is defined by the formula I where Μ represents an element of the lanthanide series, scandium or yttrium, Cp represents a cyclopentadienyl group or a derivative of a cyclopentadienyl group, Υ represents a hydrocarbyloxy group, a thiohydrocarbyloxy group, an amino group, a silylenyl group, a silyl group, cyclopentadienyl group, X represents a hydrogen atom, a halogen atom, a hydrocarbyloxy group, a thiohydrocarbyloxy group, an amino group, a silyl g a ruppu or a monovalent organic group, each L independently represents a neutral Lewis base, n is a number from 0 to 3, or where Cp and Υ are combined by a divalent group. 5. A method according to claim 4, characterized in that Υ represents a cyclopentadienyl group or a cyclopentadienium derivative |
