The invention relates to a composition comprising a rubber-modified monovinylaromatic polymer comprising: 70 wt % or more of a monovinylaromatic polymer matrix, from 2 to 12 wt % of at least one rubber, and from 0.1 to 3.4 wt % of metallocene-catalyzed poly-alpha-olefins (mPAO)
all based on the total weight of the rubber-modified monovinylaromatic polymer, with the mPAO having a kinematic viscosity of at least 950 mm.sup.2/s at 40° C. and at most 2,000 mm.sup.2/s at 40° C. as measured according to ISO 3104. The invention also relates to articles made from such composition and to the process to produce said composition and said articles.

A method for preparing a rubber composition capable of improving the physical properties of a final product is disclosed. A rubber composition is prepared by dispersing polybutene in rubber in a solution phase (PIB extended rubber). The method comprises dispersing hydrophobic extender oil and polybutene in water to prepare an extender oil/polybutene emulsion; adding the extender emulsion to a latex-shaped rubber composition and uniformly dispersing the same in a solution to prepare a rubber/extension oil/polybutene composition; and solidifying, drying and molding the composition in a latex shape through salting-out and acid precipitation. When the rubber composition is applied to a tire tread composite material, the durability, grip property and low rotational resistance are improved, thereby attaining improved braking characteristic, low fuel consumption characteristic, and wear performance.
