Abstract A novel gelatinous composition is disclosed which contains an intimate melt blend admixture of poly(styrene-ethylene-butylene-styrene)triblock copolymer having said styrene end block to ethylene and butylene center block ratio of from about 20:80 to about 40:60 and high levels of a plasticizing oil. The gelatinous composition is transparent and have a novel combination of properties including unexpectedly high elongation and tensil strength and excellent shape retention after extreme deformation under high-velocity impact and stress conditions. The gelatinous products of this invention are soft, flexible, and have elastic memory, characterized by a gel rigidity of from about 20 gram to about 700 gram Bloom. These and other properties are particularly essential for the gelatinous composition to have utility as toys, therapeutic hand exercising grips, shock absorbers, acoustical isolators, and other uses.
A reusable lint remover article comprising a gelatinous elastomer composition consisting essentially of: (a) 100 parts by weight of a high viscosity triblock copolymer of the general configuration poly(styrene-ethylene-butylene-styrene); (b) from about 300 to about 1,600 parts by weight of a plasticizer; said composition characterized by a gel rigidity of from about 20 to about 700 gram Bloom, wherein said triblock copolymer characterized by a Brookfield Viscosity of a 20 weight percent solids solution in toluene at 25° C. of at least 1,800 cps, said article is for cleaning a computer mouse, a computer keyboard, a typewriter keyboard, a camera lens, a LP record, or a material surface.
