Abstract: A thermoplastic composition comprises a thermoplastic resin (e.g., PVC) and less than 4.0 parts of a core-shell impact modifier per 100 parts by weight of the thermoplastic resin, wherein the core-shell impact modifier has a rubber content of at least 90%. A core-shell impact modifier composition comprises core-shell impact modifier particles having a rubber content that is greater than 92 wt % of the core-shell impact modifier particles. Articles of manufacture made from the thermoplastic compositions are also disclosed.

Abstract: A method of reducing gloss that results in a polyvinyl chloride (PVC) component that exhibits a reduced level of surface gloss; wherein, the PVC or other thermoplastic resin component comprises: a PVC resin; one or more process aids comprising at least one base polymer with one or more of the process aids being functionalized with about 0.5 wt. % to about 35 wt. % of a reactive epoxy, hydroxyl, or carboxylic acid functional group based on the total weight of the process aids; and optionally, at least one impact modifier. The PVC or other thermoplastic resin component exhibits a gloss reduction of at least 5 points measured at an angle of 85 degrees or less when compared to a similar PVC component in which the process aids are not functionalized.

Abstract: The invention relates to a methylmethacrylate-butadiene-styrene (MBS) core/shell polymer impact modifier containing functionalization in the shell. The functionalized MBS is useful as an impact modifier in engineering resins, and especially in blends of engineering resins, particularly where the blend contains both functional and non-functional resins. One specific engineering resin blend having excellent low temperature impact performance is a polycarbonate (PC)/polyethylene terephthalate (PET) blend with the functional MBS of the present invention.

Abstract: The addition of at least one promoter selected from the group consisting of thiosulfate salts, sulfite salts, bisulfite salts, erythorbate salts, isoascorbate salts, and combinations thereof to an aqueous treatment fluid containing a viscosifying polymer and a peroxide helps to promote the activity of the peroxide as a breaker, thus facilitating a reduction in viscosity of the aqueous treatment fluid at lower temperatures than are possible in the absence of the promoter. The promoted aqueous treatment fluid is useful as a fracture fluid to fracture subterranean formations in oil and gas recovery.
