Abstract
The invention relates to a rubber composition and its preparation having a crosslink distribution, particularly at least two types of crosslinks, its preparation, and an article of manufacture, including a tire, having a component of such rubber composition. In one embodiment the crosslink distribution can be a controlled crosslink distribution of at least two types of crosslinks. In one embodiment, such crosslink distribution relates to an inclusion in the rubber composition of an additive to promote the crosslink distribution where the additive itself has a part of the desired crosslink characteristics. The distributed crosslinks can be of different types including different length, different chemistry, and connecting different points on the crosslinked rubber chains. The distributed crosslinks can be present in different concentrations in the rubber composition. The crosslink distribution can be random or in the nature of a gradient change between domains of different crosslinks. The properties of the rubber composition can be varied by adjustment of such distributed crosslinks to promote various physical properties such as, for example, its viscoelastic properties, tear strength, abrasion resistance and green strength.
