PRODUCTION OF DYNAMICALLY CURED MIXES Russian patent published in 2014 - IPC C08J3/22 C08J3/24 C08L23/22 C08L51/06 C08L77/00 C08L23/28 B29C47/56 

FIELD: process engineering.

SUBSTANCE: invention relates to dynamically cure mixes that can be used for tire production. Production of said mix including at least one isobutylene-bearing elastomer and at least one thermosetting resin is carried out in several steps. At step (a) said thermosetting resin is mixed with at least one plasticiser in the first melt processing device to get a resinous mother mix. At step (b) said mix is pelletised prior to feeding it in the melt treatment second device intake. At step (c) said elastomer, at least one curing agent and resinous mother mix are fed into intake of the melt second treatment device. At step (d) said content of melt processing second device under conditions of dynamic curing to make dynamically vulcanised mix. In the latter, elastomer exists as a disperse phase of fine cured or partially cured particles in disperse phase of thermosetting resin.

EFFECT: good impermeability and resilience at low temperatures.
