Novel gelatinous compositions, composites, and articles are formed from an intimate melt blend admixture of one or more of a high viscosity poly(styrene-ethylene-butylene-styrene), poly(styrene-ethylene-propylene-styrene), poly(styrene-ethylene-butylene).sub.n, poly(styrene-ethylene).sub.n triblock and branched copolymers and the like, in combination with high levels or one or more selected plasticizing oil(s) to achieve improvements of compression set resistance and low gel tack.
