Title:
MICROSTRUCTURE MODIFIER FOR ANIONIC POLYMERIZATION
Document Type and Number:
WIPO Patent Application WO2003044065
Kind Code:
A3
Abstract:
Disclosed is a method for the production of optionally coupled, non-blocking polymers based on conjugated dienes and optionally monovinyl aromatic compounds by anionic polmerization in an inert organic solvent in the presence of a lithium organic compound as an initiator and a microstructure modifier and/or randomizer. Specific ether compounds are used as a microstructure modifier and/or randomizer. The polymers thus produced are particularly suitable for the production of damping material, tires and tire components (e.g. tire treads or tire sidewalls) and technical rubber articles.
