Embodiment 1

[0078] To a 1 gallon glass bottle was added 4000 ml of water and 40 g of sodium hydroxide (99% pure, purchased from Aldrich). After the sodium hydroxide was completely dissolved, 500 g of polyisobutylene succinic anhydride (Mw=1900, Mn=1000, purchased from Chevron Chemicals, trade name OLOA15500, acid value 95) was added to the bottle. The mixture was then vigorously mixed for 1 hour at 90°C. The resulting solution was a milky solution. This solution is referred to as Solution-A.

[0079] To a half gallon sized glass bottle was added 2000 ml of water and 238 g of potassium aluminum sulfate dodecahydrate (98%+ purity, purchased from Aldrich). The mixture was then vigorously mixed at 80° C. for 1 hour until the solution was completely transparent. This solution is referred to as Solution-B.

[0080] Solution-A and Solution-B were then combined while still warming with vigorous stirring. Combination produces a gel-like material. The material was washed 8 times with deionize...

Abstract

A composition includes a vulcanizable diene rubber, a silica filler, and a metal-functionalized polyisobutylene succinic anhydride derivative. In one embodiment the composition has a reduced amount of oil and may include no oil. A tire tread composition includes, a silica filler, a metal-functionalized polyisobutylene succinic anhydride derivative, a rubber matrix, an optional oil, and one or more components selected from the group consisting of carbon black, vulcanizing agent, vulcanization accelerator, tackifier resin, antioxidant, wax, peptizer, vulcanization retarder, activator, processing additive, plasticizer, pigments, and antiozonant. A method for making the rubber composition and the tire tread is also provided.

Description

technical field [0001] The present disclosure generally relates to rubber compositions. More specifically, the present disclosure relates to oil-reduced rubber compositions that include an oil substitute. Background technique [0002] In the tire industry, rubber compositions are designed to have a balance of properties such as tensile strength, tear resistance, rolling resistance, grip and handleability. Often, modifying a composition to improve one or more of these qualities makes it difficult to maintain at least one other quality. When improving such qualities as grip, tensile strength and tear resistance are highly desirable, maintaining low rolling resistance is also extremely important, especially with the increase in fuel prices and other concerns in recent years. Therefore, additives that improve the grip and / or tensile strength and tear resistance characteristics of tires and also maintain relatively low levels of rolling resistance are highly desirable. Conten...
