Abstract
The present invention relates to a modified elastomeric polymer obtained by reacting a living anionic elastomeric polymer and specific chain end modifying compound, wherein the living anionic elastomeric polymer comprises more than 70% and less than 99% by weight of butadiene units and more than 1% and less than 30% by weight of styrene units and has a vinyl bond content of from 2 to less than 10%, based on the polybutadiene fraction of the living anionic elastomeric polymer. The invention further relates to a method of preparing the modified elastomeric polymer and to an elastomeric polymer composition comprising the modified elastomeric polymer.
