THERMOPLASTIC RUBBER Russian patent published in 2010 - IPC C08L23/12 C08L23/16 C08L83/05 C08K5/05 C08K5/5313 

FIELD: chemistry.

SUBSTANCE: invention relates to thermoplastic rubber obtained through dynamic vulcanisation, which can be used to make various elastic industrial rubber products such as hoses, sealants, linings, elastic articles for the interior and exterior of automobiles, different corrugated elastic articles. The thermoplastic rubber is made from a composition consisting of ethylenepropylenediene elastomer, polypropylene, hydrocarbon oil, fine-grained filler, curing agents which include polyhydrosiloxane which contains at least two SiH groups, and a platinum catalyst. The composition also contains a higher fatty alcohol with 12-22 carbon atoms and an organophosphorus cyano-containing compound selected from an alkylcyanoethylphosphite group of general formula (NCC₂H₄O)_nP(OR')3_-n or alkylcyanoethylphophine of general formula (NCC₂H₄O)_nP(R')3_-n, where R' is an alkyl with 2-3 carbon atoms, n=1-3.

EFFECT: increased fluidity of the molten mass while retaining good deformation and strength characteristics.
