    摘要: Improvement in separating lower carboxylic acids from aqueous streams via liquid-liquid extraction with pressurized liquefied propylene and/or propane, wherein carboxylic acid is transferred from the aqueous phase into the liquid solvent phase (extract). The extracted carboxylic acids are recovered as a liquid concentrate by evaporating off the propylene and/or propane solvent from the extract at mild temperatures.

    摘要: The invention relates to an aqueous fluoropolymer coating composition for direct application to glass without the need for pre-treatment of the glass surface. The coating composition can also be used with other non-porous and porous substrates. The fluoropolymer coating contains a hydroxyl-functional fluoropolymer, and polyisocyanates. Preferably the coating composition also contains a water-dispersible hydroxyl functional polyurethane. The coating composition may exist as a 1-pack or a multi-pack coating system. The coating has excellent wet adhesion to glass, good weathering, chalking resistance, chemical resistance, and dirt pickup resistance.

    摘要: The present invention relates to foam products made with blowing agent compositions comprising at least one hydrochlorofluoroolefin (HCFO) used in the preparation of foamable thermoplastic compositions. The HCFOs of the present invention include, but are not limited to, 1-chloro-3,3,3-trifluoropropene (HCFO-1233zd), particularly the trans-isomer, 2-chloro-3,3,3-trifluoropropene (HCFO-1233xf), dichloro-fluorinated propenes, and mixtures thereof. The blowing agent compositions of the present invention are used with coblowing agents including carbon dioxide, atmospheric gases, hydrofluorocarbons (HFC), hydrofluoroolefins (HFO), alkanes, hydrofluoroethers (HFE), and mixtures thereof. Preferred HFCs used as coblowing agents in the present invention include, but are not limited too, 1,1,1,2-tetrafluoroethane (HFC-134a), 1,1-difluoroethane (HFC-152a), 1,1,1-trifluoroethane (HFC-143a), pentafluorethane (HFC-125), difluoromethane (HFC-32). The blowing agent compositions are useful in the production of low density insulating foams with improved k-factor.

    摘要: 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.
