FOAM THERMOPLASTIC GEL COMPOSITION Russian patent published in 2009 - IPC C08J9/32 C08J3/28 C08L53/02 C08K5/00 

FIELD: chemistry.

SUBSTANCE: there is disclosed foam thermoplastic gel composition containing (a) block copolymer containing at least one polymer block A made of monovinyl aromatic compound, and at least one polymer block B made of conjugated diene; (b) liquid component chosen from the group including filling oils, plasticiser and solvents compatible with said block copolymer (a); (c) thermoplastic particles foam when heated containing gas extended when heated or condensed gas, and optionally (d) photoinitiator characterised that block copolymer (a) represents a block copolymer cross-linked when irradiated and contains monovinyl aromatic compound 7 to 35 wt % of total polymer with total apparent molecular weight 50 to 1500 kg/mol and vinyl content in block B 10 to 80 mole %, where blocks B are probably hydrogenated thus residual initial ethylene unsaturation is at least 25 %. There is also disclosed production process of said foam elastic thermoplastic gel composition (versions), as well as application of said foam elastic gel composition.

EFFECT: production of low-density oil gels of improved hear resistance.
