Abstract

A composition including at least one elastomer, and a hydrocarbon polymer additive having a dicyclopentadiene, cyclopentadiene, and methylcyclopentadiene derived content of about 40 wt% to about 80 wt% of the total weight of the hydrocarbon polymer additive, a weight average molecular weight of about 100 g / mole to about 800 g / mole, and a softening point of about 110°C to about 150°C as determined in accordance with ASTM D6090.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Application Serial No. 61 / 651,756, filed May 25, 2012, the contents of which are incorporated by reference in their entirety. field of invention [0003] The present invention relates to dicyclopentadiene-based resin compositions comprising an elastomer and a hydrocarbon polymer additive having components derived from dicyclopentadiene, cyclopentadiene and methylcyclopentadiene. The invention further relates to articles made from such dicyclopentadiene-based resin compositions. Background of the invention [0004] Elastomeric compositions having a combination of performance properties such as high wet traction and low rolling resistance are commonly used in tires and other applications. Unfortunately, hydrocarbon resins added to elastomers to improve wet traction can have a negative impact on rolling resistance, and vice versa. Accordingly, resins that can increase t...
