FIELD: chemistry.
SUBSTANCE: invention concerns curable thermoplastic elastomer mixes, their obtaining and application in production of items by cast or extrusion moulding. Curable thermoplastic elastomer mix includes: (a) 15 to 60 wt % of polymer or copolymer represented by complex polyalkylenephthalate polyether, and (b) 40 to 85 wt % of linked poly(met)acrylate or polyethylene/(met)acrylate curing resin combined with free radical peroxide initiation agent and organic diene co-agent in effective amount for linking the resin during extrusion or cast moulding of curable thermoplastic elastomer mix. After linkage the polymer or copolymer represented by complex polyalkylenephthalate polyether is present in the form of continuous phase, while the resin is present in dispersed phase. Such compositions are fit for production of rubber parts with excellent resistance to effect of oil lubricants and greases.
EFFECT: optimised residual compression deformation and Shore hardness, increased elastic constant during curing.
