ELASTOMERIC COMPOSITIONS AND USE THEREOF IN ARTICLES Russian patent published in 2015 - IPC C08L23/02 C08L23/22 C08L23/28 B60C1/00 C08L77/00 

FIELD: chemistry.

SUBSTANCE: invention relates to thermoplastic elastomeric compositions. A dynamically vulcanisable alloy includes: a) at least one elastomer containing isobutylene; b) at least one thermoplastic resin, c) an anhydride-functionalised oligomer, wherein before functionalisation, the oligomer has molecular weight in the range of 750-1250, and d) a plasticiser which is selected from a group which includes tertiary amines, secondary diamines and sulphonamides, wherein the anhydride-functionalised oligomer and plasticiser are present in a ratio of 0.15-3.0, the elastomer is present in a dispersed phase in the form of fine vulcanised or partially vulcanised particles in the continuous phase of the thermoplastic resin.

EFFECT: alloy retains high Shore hardness A and acquires improved fluidity necessary for treatment.
