Abstract
PURPOSE: A rubber composition which provides vulcanizates having excellent physical properties and being almost free from migration of softener, prepared by compounding a diene rubber with a specific cyclopentadiene resin.
CONSTITUTION: To (A) 100pts.wt. of a diene rubber such as natural rubber or styrene/butadiene rubber is added (B) 4W40pts.wt. of a cyclopentadiene resin, bromine value ≤150, MW 300W104, softening point ≤200°C, prepared by cationically polymerizing (i) 35W100wt% of a (di)cyclopentadiene with (ii) 65W0wt% of at least one copolymerizable unsaturated hydrocarbon selected from the group consisting of aliphatic linear monoolefins, aliphatic linear diolefins and aromatic olefins. When the rubber composition is applied to tire treads the cutting resistance is remarkably improved.
