Claim:
A gel article in the form of a gel liner comprising a soft gelatinous elastomer composition formed from (I) 100 parts by weight of one or more hydrogenated controlled distribution styrene block copolymer(s) of the general configuration hydrogenated controlled distribution poly(styrene-isoprene/butadiene-styrene) block copolymer(s) selected from SEB-EB/SEBS, SEBS, SEPS, SEB/SEBS, SEP/SEPS, SEB/SEPS, SEP/SEBS, SEBn, SEPn, and SEEPS, wherein said hydrogenated controlled distribution styrene block copolymer(s) being a linear, radial, star-shaped, branched or multiarm copolymer, wherein n is greater than one; from (II) about 300 to about 1,600 parts by weight of one or more selected plasticizer(s) being in sufficient amounts to achieve a gel rigidity of from about 20 gram Bloom to about 1,800 gram Bloom in combination with or without (III) a selected minor amount of one or more polymers or copolymers of poly(styrene-butadiene-styrene), poly(styrene-butadiene)n, poly(styrene-isoprene-styrene)n, poly(styrene-isoprene)n, poly(styrene-ethylene-propylene), poly(styrene-ethylene-ethylene-propylene-styrene), poly(styrene-ethylene-propylene-styrene), poly(styrene-ethylene-butylene-styrene), poly(styrene-ethylene-butylene), poly(styrene-ethylene-propylene)n, poly(styrene-ethylene-butylene)n, polystyrene, polybutylene, poly(ethylene-propylene), poly(ethylene-butylene), polypropylene, or polyethylene, polyethylene copolymers selected from ultra low density poly(ethylene-octene-1 copolymers) and copolymers of ethylene and hexene, poly(ethylene-styrene) interpolymer made by metallocene catalysts, using single site, constrained geometry addition polymerization catalysts including terpolymers of poly(ethylene/styrene/propylene), poly(ethylene/styrene/4-methyl-1-pentene), poly(ethylene/styrene/hexend-1, ethylene/styrene/octene-1), poly(ethylene/styrene/norbornene), wherein said selected copolymer is a linear, radial, star-shaped, branched multiarm block copolymer or an interpolymer, wherein n is greater than one; said gel article comprising a gel with one or multiple rigidity regions, said gel multiple rigidity regions having no physically separable boundaries, or when said gel article is formed into a gel composite, wherein said gel being denoted by G, is in contact with a selected material M or in combination with one or more of a different gel, said gel composite is of the combination GnGn, GnGnGn, GnMn, GnMnGn, MnGnMn, MnGnGn, MnMnMnGnMn, MnGnGnMn, GnMnGnGn, GnGnMnMn, GnGnMnGnGn, GnMnMnGn, GnGnMnGnMnGnGn, GnMnGnMnMn, MnGnMnGnMnGn, GnGnMnMnGn, GnGnMnGnMn, GnGnMnGnMnGn, GnMnGnMnGn, MnMnMnGn or a permutation of one or more of said Gn with Mn; wherein when n is a subscript of M, n is the same or different selected from the group consisting of paper, foam, plastic, fabric, metal, metal foil, concrete, wood, glass, glass fibers, ceramics, synthetic resin, synthetic fibers or refractory materials; and wherein when n is a subscript of G, n denotes a different gel rigidity.
