Title:
TIRE COMPOSITION AND METHOD FOR MAKING THE SAME
Document Type and Number:
Japanese Patent JP2022098480
Kind Code:
A
Abstract:
To provide an improved resin to improve both wet grip and rolling resistance in a rubber composition.SOLUTION: The disclosure relates to a composition for use in tires. The rubber composition comprises a blend of a rubber component and, based on 100 pts.wt. (phr) of the rubber component, 50 to 200 phr of a filler, 0 to 25 phr of a plasticizer, and 5 to 90 phr of dimeric decarboxylated rosin (DDCR). The DDCR resin comprises 50 to 100 wt.% of polycyclic hydrocarbon compounds having one or more aliphatic, unsaturated or aromatic groups and 34-80 carbon atoms, with a molecular weight Mn of 250-900 Da, a polydispersity index of 1.0-1.35, and an oxygen to carbon ratio of less than 5%.SELECTED DRAWING: None
