Oil extended functionalized styrene-butadiene copolymer

摘要

The present invention refers to an oil extended functionalized styrene-butadiene copolymer wherein the functionalized styrene-butadiene copolymer comprises 15 to 50 wt.%, based on 100 wt.% of the copolymer, of repeating units based on styrene, 42 to 80 wt.%, based on 100 wt.% of the copolymer, of repeating units based on butadiene, and 5 to 43 wt.%, based on 100 wt.% of the copolymer, of units based on at least one functional monomer and wherein at least one extender oil is based on vegetable oils.
