Abstract:
Compositions of a semicrystalline thermoplastic and a dispersed phase of an organically modified clay are disclosed, as well as a process for making the organically modified clay, which comprises contacting the clay with at least one imidazolium salt having two long alkyl chains, or a benzimidazolium salt having two long alkyl chains in the presence of a solvent, and recovering the organically modified clay having a d-spacing of clay intercalates of at least 28Å and thermal stability at 300°C.
Abstract:
A composition comprises, based on the total weight of the composition from 79 to 99.79 weight percent of a polyester ionomer component, wherein the polyester ionomer component comprises, based on the polyester ionomer component, 0 to 40 wt.% of a non-ionomeric polyester, and 60 to 100 wt.% of a ionomeric polyester copolymer (i) non-ionomeric ester units and (ii) sulfonated ionomeric ester units, wherein the sulfonated ionomeric ester units are present in an amount from 0.05 to 5 mole percent of the total moles of ester units in the ionomeric polyester copolymer, from 0.1 to 6 weight percent of an organoclay; from 0.1 to 10 weight percent of an epoxy compound; and from 0.01 to 5 weight percent of a catalytic metal salt.
Abstract:
A composition that contains from 30 to 95 wt. %, based on the total weight of the composition, of a thermoplastic component and an effective amount of a flow-enhancing component. The effective amount of the flow-enhancing component reduces the viscosity of the composition by at least 10% compared to the viscosity of a composition comprising the thermoplastic component, but not an effective amount of the flow-enhancing component. The thermoplastic component is selected from the group consisting of polycarbonates, polyesters, and combinations thereof. The flow-enhancing component comprises b1) a component selected from the group consisting of metal oxides, metalloid oxides, metal alkoxides, metalloid alkoxides, and combinations thereof and b2) a mineral filler component. The weight ratio of component b1) to component b2) ranges from 1:25 to 25:1. A method for enhancing the flow of compositions comprising thermoplastic components is also disclosed.
Abstract:
A composition comprises a thermally crosslinked reaction product of a polyester and a carboxy-reactive material. Methods for the manufacture of the composition and articles derived from the composition are also disclosed.

Abstract:
Bio-based terephthalic acid (bio-TPA), bio-based dimethyl terephthalate (bio-DMT), and bio-based polyesters, which are produced from a biomass containing a terpene or terpenoid, such as limonene are described, as well as the process of making these products. The bio-based polyesters include poly(alkylene terephthalate)s such as bio-based poly(ethylene terephthalate) (bio-PET), bio-based poly(trimethylene terephthalate) (bio-PTT), bio-based poly(butylene terephthalate) (bio-PBT), and bio-based poly(cyclohexylene dimethyl terephthalate) (bio-PCT).
