Abstract
A method of preparing a sidewall support, the method comprising the steps of (i) providing a vulcanizable composition including an elastomer, a filler, a curative, and a eutectic composition; (ii) fabricating the vulcanizable composition into a green sidewall support; and (iii) subjecting the green sidewall support to curing conditions.
Claims21
A method of preparing a sidewall support, the method comprising the steps of:
- (i) providing a vulcanizable composition including an elastomer, a filler, a curative, an antioxidant, and a eutectic composition, where the eutectic composition is defined by the formula Cat+X−zY, where Cat+ is a cation, X− is a counter anion, and z refers to the number of Y molecules that interact with the counter anion, where the counter anion is a Lewis Base;
- (ii) fabricating the vulcanizable composition into a green sidewall support;
- and
- (iii) subjecting the green sidewall support to curing conditions.

A pneumatic tire comprising:
- (i) a tread;
- (ii) a carcass;
- (iii) an optional innerliner layer;
- (iv) a pair of sidewall supports disposed on the carcass or on the optional innerliner layer, if present, where said sidewall supports are prepared from a vulcanizable composition including an elastomer, a filler, a curative, an antioxidant, and a eutectic composition, where the eutectic composition is selected from the group consisting of a combination of a quaternary ammonium salt with a metal halide (Type I eutectic composition), a combination of a quaternary ammonium salt and a metal halide hydrate (Type II eutectic composition), a combination of a quaternary ammonium salt and a hydrogen bond donor (Type III eutectic composition), and a combination of a metal halide hydrate and a hydrogen bond donor (Type IV eutectic composition).
