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

Abstract: 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 Tg/Mn 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 Mn of 250-900 Da, and an oxygen to carbon ratio of <5%. The DDCR product has at least 50%, and up to 100% as dimeric species, with the remainder being trimeric and larger polymeric species.

Abstract: 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?C groups, and m/z (mass/charge) value of 220-280; an oxygen content of <5%; a density of 0.9 to 1.0 g/cm3 at 20° C.; and an acid value of <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).

Abstract: Intra-uterine-device meant to be inserted into the uterus, comprising an elongated stem, carrying at one end two resilient, canti-levered arms, extending sideways on either side of the stem, which stem is contained within a tube shaped sheath by means of which the device may be inserted into the uterine cavity through the cervix, after which the sheath may be pulled back, wherein the sheath narrowly encloses the stem, whereas the shape and flexibility of the arms are chosen in such manner, that the arms are easily collapsable onto the outer surface of the sheath. The arms, when relaxed, curve back towards the stem, so that they substantially form part of an ellipse, the longer axis of which coincides with the stem. The stem may at least partially be covered with a layer preventing pregnancy, which layer enhances the effect of the device. This layer may consist of a copper wire wound on the stem or of a carrier for a hormone preparation.
