Abstract:
A polyester composition comprising (a) a polyester derived from a diol and a diacid, (b) a fluoropolymer and (c) a carboxy reactive compound, where the polyester composition has a highly useful combination of (i) mechanical properties and (ii) melt strength is disclosed. Also disclosed is a process to prepare these compositions and articles therefrom.
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).

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 high flow polyester composition is disclosed, which comprises at least one polyester and at least one flow enhancing ingredient of structure, I, where, R1=NH2 or CH2OH; R2=CH3, CH3CH2 or CH2OH or any of C1-C20 alkyl group which may have one or more hydroxy group substituent, C3-C20 cycloalkyl group, C6-C20 aryl group, C1-C20 alkoxy group which may have one or more hydroxy group substituent or C6-C20 aryloxy group. A good balance of flowability and mechanical properties is obtained by controlling the amount of the said flow-enhancing ingredient. The composition further comprises reinforcing fillers, impact modifiers, a property-enhancing thermoplastic such as polycarbonate and flame retardant chemicals. The compositions are suitable for making automotive, electric and electronic parts.
