ABSTRACT:
A salt of a fatty acid is provided as a plasticizer for functionalized block copolymers of vinyl aromatics and conjugated diolefins wherein the functionalization comprises salt functionality. When this functionalized block copolymer is plasticized with the salt of a fatty acid the resulting composition will have higher tensile strengths than the raw polymer at and below the melting point of the additive and will have improved processability.
