Abstract: Polyethylene terephthalate compositions containing filler or reinforcing agent, a selected sodium or potassium salt of a selected organic polymer containing pendant carboxyl groups, and a selected low molecular weight organic ester. Articles molded from the compositions have high gloss when molded at temperatures below 110.degree. C.

Abstract: There are disclosed thermoplastic inks in the nature of high viscosity, tacky pastes which exhibit high cohesive strength, high pressure sensitivity at low temperatures, high thermal stability and low affinity for silicone surfaces. These properties make the inks particularly useful in those printing processes involving multiple elastomeric transfer members, in particular, those processes wherein silicone transfer members print successive colors onto a silicone collector which in turn transfers the multicolored print in a single step to ware or decal paper. The ink formulations consist essentially, in weight percent, of:(a) 50-80% of a pigmented, vitreous, inorganic flux;(b) 2-20% of a selected organic polymer;(c) 5-25% of a selected plasticizer;(d) 2-20% of a selected amorphous tackifying resin; and optionally,(e) up to 20% of an organic wax.

Abstract: A migration-free size for glass fibers which includes a silane coupler, lubricant and film former and is characterized by the absence of a carrier, either aqueous or organic. To provide required shelf-life, a volatile agent such as acetone is added in limited amount to block coupler-film former reaction pending use of the size.

Abstract: An interlayer film for a laminated glass, which comprises polyvinyl butyral and a plasticizer and has a T peel strength at 20.degree. C. of not more than 0.5 kg/cm, said polyvinyl butyral satisfying the following expressionY.gtoreq.-3X+486wherein X is the degree of butyralization in mole % and Y is the half-value width in cm.sup.-1 of hydroxyl absorption in the infrared absorption spectrum of the polyvinyl butyral in which the ordinate represents the transmittance and the abscissa represents the wave number.

Abstract: Dispersions and process for their incorporation with a synthetic fiber-forming polymer are provided. The dispersions comprise a polymer additive, such as titanium dioxide, and a carrier of either a C.sub.5 -C.sub.26 fatty acid ester of pentaerythritol or a C.sub.5 -C.sub.26 fatty acid ester of dipentaerythritol.

Abstract: Extrusion-cast films of high molecular weight, linear, low density ethylene copolymers which inherently have high block and high cling characteristics are compounded with a minor amount of a low molecular weight organic, such as a polyglycol, before being extrusion-cast as a thin film, the low molecular weight organic serving to substantially reduce the block, but retaining high cling characteristics.

Abstract: A polyol gel is made from 15-62 wt. % (based on the sum of polyurethane matrix plus dispersing agent) of a high molecular weight covalently cross-linked polyurethane matrix; 85-38 wt. % (based on the sum of polyurethane matrix plus dispersing agent) of a liquid dispersing agent which is firmly bonded to the matrix; and optionally, active ingredients, fillers, additives, catalysts, and mixtures thereof. The liquid dispersing agent is a polyhydroxyl compound having a molecular weight of between 1,000 and 12,000 and an OH number between 20 and 112. This dispersing agent should have virtually no hydroxyl compounds having a molecular weight below 800 present. These gel compositions may be used to make mold impressions and highly stable active-ingredient releasing compositions.

Abstract: This invention relates to a novel group of plasticizers for polyvinyl butyral wherein the plasticizer comprises a mixture of at least one triethylene glycol diester of a monocarboxylic acid having a carbon chain comprising 7 or 8 carbon atoms and at least one dialkyl adipate in which the alkyl group contains from 3 to 8 carbon atoms or at least one alkyl alkylaryl adipate.

Abstract: Polyphenylene ether resins having improved properties are described. These resins contain minor effective amounts of an antistatic agent comprising N,N-bis-(2-hydroxyethyl)-N-octyl-N-methyl ammonium para toluene sulfonate salt, preferably with polyethylene glycol ester also present. In addition to serving as an enhancer for the antistatic agent, the polyethylene glycol ester also improves such properties as odor and impact strength.

Abstract: Filled thermoplastic compositions useful as sound deadening sheeting having improved tensile elongation are obtained by blending about 5-60 percent by weight of a mixture of at least two copolymers of ethylene, having specified polar comonomer contents, about 40-90 percent by weight of filler, 0-15 percent by weight of plasticizer selected from the group consisting of processing oils, polyesters, polyethers and polyether esters, and optionally modifying resins such as elastomeric polymers and certain other ethylene and propylene homo- and copolymers.

Abstract: Polymers of esters of methacrylic acid having an average chain length of about 6 to about 50 mers are prepared by an anionic polymerization reaction, carried out in the presence of a chain-regulating alcohol and a catalytic amount of an alkoxide anion, in which control of the molecular weight and molecular weight distribution of the polymer are achieved by regulating the ratio of the total quantity of alcohol employed to the total monomer charge. These polymers, their hydrolysis products, and their derivatives have a wide variety of applications, including use as components in films, coatings, fibers, impregnants, adhesives, printing inks, and binders, and use as modifiers, plasticizers, melt flow improvers, and leveling agents.

Abstract: The inclusion of a small amount of an ester-type plasticizer in the rubber polymerization recipe in the production of rubber-modified high nitrile copolymer resins produces resins having markedly improved impact resistance at both low and high temperatures.

Abstract: A polyester based composition comprising sodium citrate as a nucleating agent.

Abstract: The use of a group of diester compounds that are particularly effective as plasticizers in polyvinylchloride-resin formulations and articles made therefrom. These compounds are the diesters of alkanedicarboxylic acids and alkanolethers. They are prepared by the direct esterification reaction of dicarboxylic acids with alkanolethers or by the trans esterification reaction of diesters with the corresponding alkanolethers.
