A foam reduction agent consisting of dibasic esters is shown and a process using a liquid contact with polystyrene foam wherein the higher boiling temperature of the dibasic esters and contact with the liquid provides a volume reduction process and less evaporation loss as well as safer transportation of the chemicals and the polystyrene in its reduced state. The resulting reduced sludge is also recyclable to superior quality raw polystyrene foam beads and the reduction agents are recoverable fo…

Polymer compositions comprised of small, dry polyacrylamide particles may be dispersed into water at industrially useful rates to form aqueous compositions, by separating the particles from each other and bringing them into contact with a moving stream of water in the manner described herein. The resulting aqueous compositions may be used as a treating solution in diverse applications such as flocculants in water treating, papermaking, mining, oil field, and biotechnological separations.

Laminating wax compositions comprising petroleum wax containing 1 to 50 weight percent of solid atactic propyleneethylene terminal block copolymer.

The zinc or manganese salt of 3,5-di-tert-alkyl-4-hydroxybenzoic acid, in combination with either a 2-hydroxybenzophenone or a 2-(2H-benzotriazol-2-yl)phenol ultraviolet absorber, provides a highly effective synergistic stabilizer system for TiO.sub.2 -pigmented polymers.

Conjugated dienes are polymerized by a new catalyst system which permits control of the molecular weight and gives a more easily processed product than obtained with an Alfin-type of polymerization. This catalyst system comprises: (1) sodium allyl compound having 3-10 carbon atoms, (2) a sodium alkoxide or aryloxide of 1-10 carbon atoms, and (3) an alkyl aryl ether, such as an anisole. The diene polymers produced by this process have controllable molecular weights in the range of 5,000-500,000, …

The present invention is directed to a water- and oil repellency-imparting preparation for fibrous and other substrates, the preparation comprising a fluorinated polymer and a tacking monomer, oligomer or polymer containing at least one anhydride functional group or a group capable of forming an anhydride functional group, optionally together with an anhydride-forming catalyst, such as sodium hypophosphite. The preparation can further optionally comprise other additives such as, for example, an …

Herein is disclosed an emulsion, comprising an oxygen scavenging polymer, water, and a surfactant. The emulsion can be formed by first forming an emulsion comprising at least one monomer, water, and the surfactant, and polymerizing the monomer. Once formed, the emulsion can be used to form an oxygen scavenging packaging article by coating at least one surface of the packaging article or contacting two surfaces of the packaging article with the emulsion, and evaporating water from the emulsion-co…

Novel compositions and methods are disclosed for manufacturing an artificial prosthesis, whether for medical, dental or cosmetic use. The compositions include a family of monomeric esters having increased solvency and decreased volatility.

A curable material useful as thermal material comprises at least one vinyl-terminated silicone oil; at least one conductive filler; and at least one hydrogen terminated silicone oil. The hydrogen terminated silicone oil is used to reduce a shear modulus G’ of the cured thermal interface material.

Fillers surface-modified by treatment with an organosilane- and/or organosiloxane-containing agent for preparing filled polyamide compositions.
