The present disclosure provides an oil-extended olefin block copolymer composition. The oil-extended olefin block copolymer composition includes an olefin block copolymer, an oil, and a surface-active agent and may optionally include an olefin-based polymer. The oil-extended olefin block copolymer composition advantageously exhibits reduced, or no, oil-bleed.

The present technology relates to ultra-low VOC compositions comprising asphalt, a softener, clay, a surfactant and one or more polymeric adhesives. The compositions may optionally include functional fibers, fillers and other additives. The present technology also includes methods of manufacturing and using such compositions in coating, sealing, waterproofing and other applications.

Polyester-based films contain certain copolyesters (A) and polyester plasticizers (B). The copolyesters (A) may be selected from those in which the force required to stretch a film of the copolyester (A) by itself, from 2× to 5×, increases by less than 200%. The polyester plasticizers (B) have a weight-average molecular weight of 900 to 12,000 g/mol, and contain (i) a diol component comprising residues of diols having 2 to 8 carbon atoms, and (ii) a diacid component comprising residues of dicarboxylic acids having 4 to 12 carbon atoms. These polyester-based films are particularly useful for preparing ultra-thin LCD or OLED polarizers, because they can be stretched very thin with a high stretch ratio at lower temperatures.

A heat-sensitive functional additive is protected from multiple heat histories by being mixed at ambient temperature with a pre-formed masterbatch, for let down into thermoplastic resin at the time of final-shaping of the plastic article.

A fluorine-containing dispersion is disclosed, the solid content of the fluorine-containing dispersion including a fluorine-containing polymer powder and polyimide. The fluorine-containing polymer powder has a mass ratio greater than 85% in the solid content, and the polyimide has a mass ratio less than 15% in the solid content. An average particle size of the fluorine-containing polymer powder is less than or equal to 3 μm. A method of preparing the fluorine-containing dispersion, and a fluorine-containing composite film made using the fluorine-containing dispersion are also disclosed.

A unique monobenzoate useful as a plasticizer in polymeric dispersions, such as plastisols and melt compounds. The monobenzoate comprises 3-phenyl propyl benzoate, a benzoate ester heretofore known as a flavoring and fragrance agent, but not previously utilized as a plasticizer in polymeric applications. Depending on the application, the advantages rendered by the use of the inventive monobenzoate include, among other things, excellent solvating properties, low viscosity, viscosity stability, and improved rheology, as well as health, safety and environmental advantages over traditional plasticizers. The monobenzoate may be used alone or in combination with a variety of plasticizers, including but not limited to phthalates, terephthalates, dibenzoates, other monobenzoates, or 1,2-cyclohexane dicarboxylate esters, and mixtures thereof.
