The present invention relates to hydrolytically stable multi-purpose polymers that are polymerized from a monomer mixture comprising: at least one amino-substituted meth(acrylate) (ASMA) monomer or salt thereof; and at least one nonionic vinyl (NIV) monomer, wherein the monomer mixture optionally comprises one or more of at least one vinyl associative (VA) monomer; at least one vinyl surfactant (VS) monomer; and/or at least one polymerizable silicone macromer (PSM) and wherein the monomer mixture further optionally comprises one or more of at least one crosslinking (XL) monomer; at least one chain transfer agent (CTA); and/or at least one polymeric stabilizer. The multi-purpose polymers of the present invention can also be prepared from monomer mixtures containing chain transfer agents or other functional components commonly utilized in polymerization process.

Hydrolytically stable multi-purpose polymers

Disclosed are multi-staged acrylic based core-shell polymers comprising a linear core polymer and at least one subsequently polymerized shell polymers is crosslinked. The core-shell polymers surprisingly provide desirable rheological, clarity, and aesthetic properties in aqueous surfactant containing compositions, particularly at low pH.

Structured acrylate copolymer thickeners

A method for increasing the efficacy of hydrophobically modified (meth)acrylic based polymers to increase the critical micelle concentration of a surfactant composition by attenuating the degree of neutralization (DN) of the polymer is disclosed.

Irritation mitigating polymers and uses therefor

Disclosed are multi-purpose polymers that are the polymerization product of a monomer mixture comprising at least one amino-substituted vinyl monomer; at least one nonionic vinyl monomer; at least one associative vinyl monomer; at least one semihydrophobic vinyl surfactant monomer; and, optionally, comprising one or more hydroxy-substituted nonionic vinyl monomer, crosslinking monomer, chain transfer agent or polymeric stabilizer. These vinyl addition polymers have a combination of substituents, including amino substituents that provide cationic properties at low pH, hydrophobic substituents, hydrophobically modified polyoxyalkylene substituents, and hydrophilic polyoxyalkylene substituents. The polymers provide surprisingly beneficial rheological properties in acidic aqueous compositions, and are compatible with cationic materials. The multi-purpose polymers are useful in a variety of products for personal care, health care, household care, institutional and industrial care, and industrial applications.

Multi-purpose polymers, methods and compositions

Dimethicone copolyol polymers are synthesized from dimethicone copolyol macromers. Polymers containing the macromer repeating units are useful in a variety of applications including personal care, textile and industrial formulations to deliver softness, lubricity, fixative, humidity resistance, water repellency, gloss, surface modification, and surfactant properties.

A toughener comprising a trithiocarbonate polymer having an epoxy end group is described which is utilized with various thermosettable polymers such as epoxy, polyurethane, and the like. A toughened composition is made by curing the thermosettable polymer and the toughener utilizing various curing agents.

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&deg; to about 150&deg; 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. The reaction products have superior oxidative resistance in the Oxidation Corrosion Stability Test (OCS) and Vapor Phase Coker Test over dehydrocondensation products produced under other conditions and are useful in lubricant composition, especially in synthetic ester fluid lubricants such as turbine engine oils.

Lubricant composition

A process for monoalkylating diphenylamine using a clay catalyst is disclosed which results in a reaction product having substantial amounts of desirable monoalkylated diphenylamine and minimal amounts of less desirable disubstituted diphenylamine and unsubstituted diphenylamine. The disclosed process uses clay catalysts which favor monoalkylation over dialkylation and specific conditions such as reaction temperature, mole ratios of alkylating olefin to diphenylamine, reaction times, and catalyst amounts. Preferred olefins are diisobutylene and linear alpha olefins having from 6 or 8 to 18 carbon atoms. When more than 1 wt. % residual unreacted diphenylamine is present it may be converted to alkylated diphenylamine by reacting with styrene, alpha-methylstyrene or isobutylene.

A process for monoalkylating diphenylamine using clay catalyst is disclosed which results in a reaction product having substantial amounts of desirable monoalkylated diphenylamine and minimal amounts of less desirable disubstituted diphenylamine and unsubstituted diphenylamine. The disclosed process uses clay catalysts which favor monoalkylation over dialkylation and specific conditions such as reaction temperature and mole ratios of alkylating olefin to diphenylamine.

Disclosed is a method for decolorizing alkylated diarylamines, which have been made using aluminum chloride catalyst, by mixing and optionally heating the colored diarylamine with clay, then separating the decolorized diarylamine from the clay. Alternatively, the alkylated diarylamines, which have been made using aluminum chloride catalyst, may be decolorized by passing the diarylamines through a filter medium comprising clay.

Disclosed are processes for the preparation of an azonitrile initiator having both a low salt and low water content of the formula ##STR1## This initiator is prepared by reacting a keto acid of the formula ##STR2## with M(CN).sub.x, a hydrazine source, and hydrochloric acid to form ##STR3## The hydrazo intermediate is reacted with chlorine gas in the presence of acetone to oxidize the hydrazo intermediate to the azonitrile initiator. After oxidation, the reaction mixture is permitted to separate into layers. The bottom aqueous layer is removed and discarded. The upper acetone-azonitrile initiator level is treated with solid calcium chloride or a saturated calcium chloride or sodium chloride solution. This salting out procedure generates an additional water layer that further contains (M(Cl).sub.x. The final acetone-azonitrile initiator solution has a low salt and low water content. R.sub.1 is an alkyl group containing from about 1 to about 12 carbon atoms, R.sub.2 is non-existent or an alkylene group containing from 1 to about 12 carbon atoms, or a cycloalkylene or alkyl cycloalkylene group containing from about 3 to about 12 carbon atoms, and M is a metal comprising lithium, sodium, potassium, magnesium, or calcium.
