摘要：
This invention relates to preparation of silica-containing EPDM based rubber compositions and their use as components of articles of manufacture such as, for example, tires and industrial products. Such preparation relies upon phase mixing of EPDM based rubber compositions which contain particulate reinforcement, such as for example precipitated silica, which may optionally include exfoliated clay reinforcement, to create an enhanced EPDM rubber composition. In one aspect, the invention relates to a pneumatic rubber tire with a visible outer sidewall rubber layer comprising such rubber composition.
