Fluffy, strong, solid elastic gels, articles and method of making same
First Claim
1. A gel comprising a fluffy, solid, strong elastic gelatinous elastomer composition, Gn, exhibiting resistance to elastic deformation, capable of shape-memory recovery, being dimensionally stable formed from (I) 100 parts by weight of at least one or more a linear, multi-arm, branched, or star shaped high viscosity block copolymer, (II) about 300 to about 1,600 parts by weight of a plasticizing oil, (III) a selected amount of one or more heat expandable plastic or synthetic particulates of material dispersed in one or more predetermined ordered or separate phases, said dispersed particulate material being capable of producing a predetermined selected volume of closed cell particulate dispersion forming said gel, wherein said gel having a density of at least about 0.70 g/cm3, a gel rigidity of from about 20 to about 3,000 gram Bloom, and an elongation of at least 200%, said gel capable of being formed with or physically interlocked with a selected substrate material, Mn, to form one or more combinations of a gel-substrate composites including a sequential addition or permutation of said combinations of one or more gels of the same or different gel rigidity and one or more substrates of the same or different material;
- said gel formed with or without (IV) one or more of a selected polar polymer and in combination with or without (V) one or more of a selected crystalline or non-crystalline polymer or copolymer.

Abstract
Novel fluffy, solid, strong elastic gels exhibiting resistance to elastic deformation, capable of shape-memory recovery, being dimensionally stable and having a density of at least less than about 0.60 g/cm3, a gel rigidity of from about 20 to about 3,000 gram Bloom, and an elongation of at least 200% can be formed with or physically interlocked with selected material substrates to form composites including any sequential additions or permutations of said combinations of gels and substrates.
