Estimating the term…
The block copolymers according to the invention which are based on conjugated diolefins and polar monomers and are prepared in the presence of catalysts based on the rare earth metals have a high cis-1,4 content in the polydiene block and, because of their polar polymer part and their non-polar diene polymer part, can be used as agents which impart compatibility in the preparation of vulcanizates with a filler content for the production of tires and tire components, as a filler in the preparation of such vulcanizates, and as a blend component in the preparation of thermoplastic elastomers or in the modification of thermoplastics.
Block copolymers based on conjugated dienes and polar monomers, wherein the block copolymers comprise the polymerized conjugated dienes in amounts of 5 to 95 wt. % and the polymerized polar monomers in amounts of 95 to 5 wt. %, the polymerized dienes having a cis-1,4 content of ≧60 wt. %.
A process for the preparation of block copolymers based on conjugated dienes- and polar monomers, wherein the block copolymers comprise the polymerized conjugated dienes in amounts of 5 to 95 wt. % and the polymerized polar monomers in amounts of 95 to 5 wt. %, the polymerized dienes having a cis-1,4 content of ≧60 wt. %.
Vulcanizates with a filler content for the production of tires and tire components comprising block copolymers based on conjugated dienes and polar monomers, wherein the block copolymers comprise the polymerized conjugated dienes in amounts of 5 to 95 wt. % and the polymerized polar monomers in amounts of 95 to 5 wt. %, the polymerized dienes having a cis-1,4 content of ≧60 wt. %.
A thermoplastic elastomer containing block copolymers based on conjugated dienes and polar monomers which comprise the polymerized conjugated dienes in amounts of 5 to 95 wt. % and the polymerized polar monomers in amounts of 95 to 5 wt. %, the polymerized dienes having a cis-1,4 content of ≧60 wt. %.
A blend material for the modification of thermoplastics comprising block copolymers based on conjugated dienes and polar monomers which comprise the polymerized conjugated dienes in amounts of 5 to 95 wt. % and the polymerized polar monomers in amounts of 95 to 5 wt. %, the polymerized dienes having a cis-1,4 content of ≧60 wt. %.
