摘要： Disclosed are compositions comprising dimeric decarboxylated rosins (DDCRs), methods for making them, and applications thereof. DDCR of purity from 50-100 wt. % is obtained by decarboxylating a dimeric rosin acid or by dimerizing a decarboxylated rosin, in the presence of a catalyst, followed by one or more purification steps separation on differences in boiling point. The isolated DDCR fractions display unexpectedly high T g /M n ratios, softening points and viscosities, and low polydispersities. The DDCR product 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 M n of 250-900 Da, and an oxygen to carbon ratio of

摘要： The disclosure relates to a composition for use in tires. The rubber composition comprises a blend of a rubber component and based on 100 parts by weight (phr) of the rubber component, from 50 to 200 phr of a filler, from 0 to 25 phr of a plasticizer, and from 5 to 90 phr 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 M n of 250-900 Da, a polydispersity index of 1.0-1.35, and an oxygen to carbon ratio of
