MIXTURES OF FUNCTIONALISED DIENE CAOUTCHOUCS WITH TRIMETHYLOLPROPANE AND FATTY ACID, METHOD OF OBTAINING THEREOF AND APPLYING THEREOF Russian patent published in 2015 - IPC C08L21/00 C08K3/36 C08K5/04 C08J3/20 B60C1/00 

FIELD: chemistry.

SUBSTANCE: invention relates to functionalised diene caoutchoucs with trimethylolpropane and a fatty acid, to a method of their obtaining and to their application for the production of automobile tyre treads. A vulcanising mixture of caoutchoucs contains the diene caoutchouc, functionalised with carboxyl and/or hydroxyl groups and/or their salts. The functionalised diene caoutchouc contains 40-100 wt % of 1,3-butadiene and 1-60 wt % of styrene. The content of bound functional groups and/or salts constitutes 0.02-5.0 wt % counted per 100 wt % of the diene caoutchouc. The mixture contains a light filling agent, trimethylolpropane, a fatty acid and other additives to caoutchoucs.

EFFECT: invention makes it possible to obtain automobile tyres which have an improved complex of properties: wet skid resistance, low rolling resistance and high wear resistance.
