Abstract: The present invention relates to the use of cycloaliphatic diamines as cosolvents for hydrophobic amines in aqueous solution. The cycloaliphatic diamines of the present invention have a formula: where n is 1 or 2, each R is independently selected from a group consisting of: hydrogen, a 1 to 6 carbon aliphatic, and a 0 to 6 carbon containing amine, wherein each R is chosen such that the cosolvent amine comprises at least two amine groups; and a quantity of water to maintain said solution as a homogeneous phase. The cosolvent diamines have particular utility in the formation of water based epoxy resin curing agents. Superior water miscibility is achieved for hydrophobic amines through the use of cycloaliphatic amines as compared to conventional cosolvents.

Abstract: The present invention relates to a method for solubilizing polystyrene in a fatty acid ester, whereby the resultant polystyrene fatty acid ester composition can be used in a variety of polymeric applications, including forming an improved polyester. The present invention also relates to the resultant polystyrene fatty acid ester composition.

Abstract: Crosslinker compositions consisting essentially of 50 to 95 weight percent monomeric C1 to C8 alkoxymethyl melamine derivatives containing not more than about 0.20 wt. % of imino (>N—H) groups. Such compositions further comprise 5 to 50 weight percent oligomeric C1 to C8 alkoxymethyl melamine derivatives and are useful for low temperature curing of functional resins, e.g. with active hydroxyl groups, for wood, automotive, appliance, coil and other coatings.

Abstract: The invention provides an N-alkenyllactam having at least a 6-membered lactam ring, stabilized by phenothiazine and/or derivatives thereof, and a process for the stabilization of N-alkenyllactams.

Abstract: A sealing composition including ethylene-vinyl acetate copolymer (EVA), a cross-linking agent, and either a polymerization inhibitor or chain transfer agent. A method of sealing a device between two substrates through the following steps of; forming a layered structure by interposing the device sandwiched with two sheets or films made of the sealing composition in between two substrates to make a layered structure; deaerating the layered structure by heating under reduced pressure; unit the layered structure by curing (cross-linking) ethylene-vinyl acetate copolymer. By controlling an initial curing rate of the EVA sealing composition, sealing can be carried out with good productivity and high yield without problems of left bubbles and poor adhesion.

Abstract: Disclosed are compositions for shortstopping free radical emulsion polymerizations and stabilizing polymers produced from the corresponding emulsion processes. Such compositions include at least one hydrophillic radical scavenger (i.e, shortstopper) and at least one hydrophobic radical scavenger. The compositions are preferably targeted for applications in the emulsion processes of rubber latexes. These compositions exhibit excellent performance not only as shortstoppers of free radical emulsion polymerizations but also as stabilizers of the corresponding polymers. Thus, the compositions prevent additional polymerization in the particles without requiring additional stabilizer even after such polymers are steam stripped. They do so without the use of chemicals which carry a high safety, health, or environmental risk.

Abstract: Rubber and plastic accelerator formulations of the present invention are directed to formulations containing an accelerator compound comprised of an organic-based quaternary ammonium salt. Preferably, the accelerator compound of the present invention is comprised of a quaternary ammonium salt selected from the group consisting of trimethylbetahydroxyethyl ammonium hydroxide (TMBHEAH), carboxymethyltrimethyl ammonium hydroxide (CMTAH), methylallylbenzylphenol ammonium iodide, benzyltriethyl ammonium chloride, hexadecyltrimethyl ammonium chloride imidazolium compounds. As particularly preferred embodiments, the accelerator formulations are comprised of a choline based compound comprised of trimethylbetahydroxyethyl ammonium hydroxide and/or of a betaine compound comprised of carboxymethyltrimethyl ammonium hydroxide.

Abstract: A cyanurate compound having three oxetane ring groups and represented by the general formula (1): wherein R1 represents a member selected from the group consisting of a hydrogen atom and alkyl groups having 1 to 6 carbon atoms, is useful as a photosetting monomer or thermosetting monomer, and thus is used, together with a hardening agent, for example, a polycarboxylic anhydride and a catalyst, for example, an amine, a carboxylic acid metal salt or a protonic acid, to provide an organic hardening composition usable for producing electronic materials, for example, resists.

Abstract: A method and product which provides a solid, non-powdered homogeneous form to liquid and low melting point solid compounds which facilitates stability, storage, dispersability and handling and which may be added directly to formulations requiring the liquid compound or low melting point solid compound. The liquid or low melting point solid ingredient is combined with a binder which is comprised of at least a wax and thermoplastic polymer. During the method of forming the product, both the binder and the liquid compound (or low melting point solid compound) pass through a liquid phase during which they are mixed. The product is then formed and cooled.

Abstract: A crosslinkable composition of a polymeric thermoplastic and/or elastomeric material which is susceptible to scorching when processed at elevated temperatures, prior to crosslinking, in the presence of a free radical initiator, is protected against such scorching by the incorporation therein of a mixture of at least one hydroquinone compound and a sulfur accelerator. This mixture may also contain at least one monomeric allylic, methacrylic, acrylic or diene type coagent. The mixture exhibits a synergistic effect resulting in improved scorch protection for peroxide cured systems when compared with the protection afforded by the components singly.

Abstract: (Meth)acrylate functional compound which is the reaction product of a cyclic secondary amine and a poly(meth)acrylate having at least three acrylate or methacrylate groups, useful for radiation curable coating or ink composition having low viscosity, low volatility, and high cure rate under radiation. Process of preparing a coating or ink composition using such compound. Radiation cured coating or ink based on such composition. Coated or printed article having such a cured coating or ink based on such composition.

Abstract: This disclosure is directed to an antioxidant compound which reduces the rate at which insoluble sulfur converts to a migratable form of sulfur in an unvulcanized compound.
