ELASTOSOL, METHOD IF ITS SYNTHESIS, METHOD OF SYNTHESIS OF HOMOGENEOUS RUBBER-LIKE PRODUCT Russian patent published in 2000 - IPC

FIELD: chemistry of polymers, rubber industry. SUBSTANCE: invention describes the novel elastogel that has: (a) linear or branched block-copolymer as small powder (size particle is 200 mcm or less) consisting of at least block A containing at least 80 weight % of monovinyl aromatic compound and 20 weight %, not above, of optionally hydrogenated coupled diene compound, and polymeric block B consisting of 80 weight %, not less, of optionally hydrogenated coupled diene and 20 weight %, not above, of monovinyl aromatic compound where the content of monovinyl aromatic compound is at least 40 weight % as for the total amount of block-copolymers, and (b) rubber-compatible liquid plasticizer taken at weight ratio (a) : (b) from 0.1 to 10. Invention describes also method of its synthesis and method of rubber-like product producing. Invention provides the development of elastosol that can be treated by the modern plastic-sol technology at low temperature. EFFECT: improved method of synthesis. 10 cl
