Abstract
The present invention relates to oil-extended styrenic block copolymer compositions that include a thermoplastic polymer, such as polystyrene, and a styrenic block copolymer, especially a linear styrene-butadiene-styrene triblock copolymer, with a styrene content less than 23 percent by weight, based upon total composition weight. The compositions yield very thin polymeric films with satisfactory physical properties.
