Abstract
Official abstract text for this publication.
The present invention provides a rubber composition comprising (a) a liquid polymer, (b) polymer nanoparticles, and (c) a rubbery matrix. The composition may comprise less or even no aromatic oil. Rubber articles manufactured from such composition, such as tires and power belts, have gained improved reinforcement and controllable hysteresis properties.
First claim
Opening claim text (preview).
The invention claimed is: 1. A composition made by a method comprising: in a liquid hydrocarbon medium, polymerizing conjugated diene monomers to produce a poly(conjugated diene) block; in a liquid hydrocarbon medium, copolymerizing the poly(conjugated diene) block with a mixture of mono-vinyl aromatic monomer and multiple-vinyl aromatic monomer to form cross-linked core-shell nanoparticles; combining the nanoparticles with a liquid polymer and a rubber matrix to form a compos…
