| titleOfInvention | Chain-terminated polyolefins designed to improve tire adhesion with wet road surface and tire tread resistance |
| abstract | FIELD: chemistry.SUBSTANCE: present invention relates to propylene-based polymers which can be used as modifiers for tire treads. Described is a tire tread composition containing a reaction product of components whose content in terms of weight of the composition ranges from: 5 to 75 wt. % diene elastomer; from 20 to 80 wt. % of filler; vulcanising reagent and from 5 to 30 wt. % functionalised with aminoalkylsilyl polyolefin (PO-aminoalkyl-Si), functionalised with alkylsilane of polyolefin or polyoxymethylene polyolefin functionalised with alkoxysilane or mixture thereof, each of which contains a polyolefin portion and a functional group attached thereto, where the polyolefin portion of the functionalised polyolefin has weight-average molecular weight (Mw) in range of 500 to 300,000 g/mol, in which the amino-alkylsilyl-functionalised polyolefin is a reaction product of a vinyl-terminal end polyolefin (VOC)-containing group, and a hydrosilylation reagent or epoxidation reagent, followed by treatment with an aminosilane-containing reagent. Method of balancing working characteristics of tire adhesion with wet road surface and rolling resistance of tire tread comprises: combining at least in terms of composition weight from 20 to 80 wt. % of filler, from 5 to 75 wt. % of diene elastomer, vulcanising reagent and from 5 to 30 wt. % of functionalised polyolefin to obtain tire tread, functionalised polyolefin is a polyolefin (PO-aminoalkyl-Si) functionalised with aminoalkylsilyl, an alkylsilane functionalised polyolefin or an alkoxysilane-reacted polyolefin or mixture thereof, each of which contains a polyolefin portion and a functional group attached thereto, where the polyolefin portion of the functionalised polyolefin has weight-average molecular weight (Mw) in range of 500 to 300,000 g/mol, in which the amino-alkylsilyl-functionalised polyolefin is a reaction product of a vinyl-terminal end polyolefin (VOC)-containing group, and a hydrosilylation reagent or epoxidation reagent, followed by treatment with an aminosilane-containing reagent; in which the functionalised polyolefin is selected and/or added in an amount which increases hysteresis in the tire adhesion area with wet road surface (0 °C) and reduces hysteresis in rolling resistance region (60 °C) without changing Tg of the whole compound by more than 10 % compared to its initial value.EFFECT: technical result is providing excellent adhesion of tire with road surface, low rolling resistance with low wear of tread.23 cl, 1 dwg, 3 tbl, 8 ex |
