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 Mof 250-900 Da, a polydispersity index of 1.0-1.35, and an oxygen to carbon ratio of <5%.

Tire composition and method for making thereof

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/Mratios, 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 Mof 250-900 Da, and an oxygen to carbon ratio of &#x3c;5%. The DDCR product has at least 50%, and up to 100% as dimeric species, with the remainder being trimeric and larger polymeric species.

Biorenewable hydrocarbon compositions and their uses

The disclosure relates to a biobased metal-working fluid (MWF) composition and method for making same, and more particularly metal-working fluid with biobased lubricants with improved emulsion stability. At least 50 wt. % of the base oil component in the MWF concentrate is a plant-derived liquid decarboxylated rosin acid oil ('DCR'). The DCR comprises 50 to 100 wt. % of tricyclic compounds having 18-20 carbon atoms, one or more C&#x2550;C groups, and m/z (mass/charge) value of 220-280; an oxygen content of &#x3c;5%; a density of 0.9 to 1.0 g/cmat 20&#xb0; C.; and an acid value of &#x3c;10 mg KOH/g. The resulting MWF is characterized as having comparable if not better performance compared to a MWF containing only mineral oil (e.g., Group I or Group II).

Metal-working fluid compositions and methods for making

An oligoester composition is disclosed, which is a reaction product of a reactant mixture comprising one or more rosins selected from the group consisting of tall oil rosin and gum rosin; at least 15% by weight of one or more monocarboxylic acids comprising 6-36 carbon atoms; and one or more polyhydric alcohols comprising 2-36 carbon atoms, wherein each hydroxyl group of the polyhydric alcohol is separated from the other hydroxyl groups by at least 2 carbon atoms. A method for preparing an oligoester composition is also provided. Also disclosed is an oligoester composition which is an esterification reaction product of one or more rosins, one or more monocarboxylic acids, one or more polyhydric alcohols, and optionally one or more polycarboxylic acids. The composition has a weight average molecular weight of from 500 g/mol to 8,000 g/mol and a Tof between &#x2212;80&#xb0; C. and 100&#xb0; C.
