Abstract: Disclosed are sunscreen compositions comprising zinc oxide and at least one of an effective amount of carbomer and an effective amount of C10 to C30 alkyl acrylate crosspolymers. The compositions most preferably utilize an oil in water emulsion. Also disclosed are related processes for producing and using such compositions.

Abstract: Talc is combined with polyurethane to facilitate crystallization of a polyurethane composition, particularly a polyester-based polyurethane composition. The addition of talc can allow for more rapid formation of products by, for example, injection molding, compression molding, extrusion, and film formation techniques.

Abstract: A rheology modifying copolymer composition containing a cross-linked copolymer of unsaturated carboxylic acid, a hydrophobic monomer, a hydrophobic chain transfer agent, a cross linking agent, and, optionally, a steric stabilizer, provides increased viscosity in aqueous electrolyte-containing environments.

Abstract: An antioxidant composition suitable for ester fluid lubricants is the reaction product of diphenylamine and N-aryl naphthylamine in the presence of an organic peroxide. The mole ratio of diphenylamine:N-aryl naphthylamine is about 1:1 to about 10:1. This results in more oligomeric reaction products and significantly less unreacted monomeric residual reactants. The resultant product composition comprises DPA homo-oligomers and DPA-NPA cross oligomers. The diphenylamine and N-aryl naphthylamine are desirably substituted with alkyl groups having from 1 to 20 carbon atoms or styryl groups. The reaction temperature is preferably about 130° to about 150° C. Controlled reaction conditions allow the use of solvents with extractable hydrogen atoms without producing significant amounts of dehydrocondensation between the solvent and the diamines.

Abstract: A high elongation, low 100% modulus composition comprises a copolymer dispersed in a continuous phase polysiloxane. The copolymer is made from high amounts of at least a monomer which is capable of forming a low Tg polymer and relatively low amounts of at least a monomer which is capable of forming a high Tg polymer. The monomer forming the low Tg polymer can be an alkyl acrylate whereas the monomers forming the high Tg polymer can be a vinyl ester, an acrylonitrile or derivatives thereof, a vinyl substituted aromatic such as styrene, an alkyl methacrylate, and the like. The composition has good adhesion to substrates as well as good viscosity aging, and can be utilized in caulks or sealants.
