Processes to prepare aqueous polymer dispersions are provided, as well as compositions thereof, which have high solids content (e.g., 50%) with low viscosity. The process uses a selective hydrophilic macro-RAFT agent of formula (I), and is substantially free of surfactants. This process can be used to make latex polymers with good stability, which can be used widely in coatings (e.g., architectural paints, stone paints, industrial coatings, wood coatings, etc.), adhesives, sealants and mastic compositions.

Process for the preparation of high-solids, low-viscosity latex using selective hydrophilic macro-raft agents

Disclosed are ethylenically unsaturated salts of allyl (poly)ether sulfates utilized as reactive surfactants or emulsifiers during emulsion polymerization.

Polymerizable surfactants having water whitening resistance and methods for use

Disclosed are novel substituted catechol monomers, polymers made with the substituted catechol monomers, pH responsive polymers made with the substituted catechol monomers, and related methods. Also provided is a method of preparing an aqueous coating composition such as a latex paint including the above components.

Substituted catechol monomers, copolymers and methods for use

Disclosed are novel catechol dditives and the like, methods of preparing, as well as compositions and methods using such compositions in various applications. Also provided is a method of preparing an aqueous coating composition such as a latex paint including the above components.

Substituted catechol additives in coatings and methods for use

Disclosed are novel substituted catechol polymeric dispersants and related method of preparing. Also disclosed are methods of dispersing at least one pigment comprising the following steps: contacting an aqueous solution containing at least one pigment with the polymeric dispersant copolymers as described herein.

Substituted catechol polymeric dispersants

Paint, clear coat, stain, adhesive, or other aqueous formulations that contain at least one [(dimethylamino)alkyl]-imino-dialcohol and a alkyd emulsion, polymer latex or polyurethane dispersion binder. Also disclosed are methods for manufacture and use of these formulations. The [(dimethylamino)alkyl]-imino-dialcohols provide aqueous formulations having low odor and reduced volatile organic compounds (VOC). The [(dimethylamino)alkyl]-imino-dialcohols also aid in dispersing pigment and other solids so less co-dispersant is needed for aqueous paint or coating formulations.

Disclosed are novel tri-substituted aromatic-alkoxylated polymeric dispersants and related method of preparing. Also disclosed are methods of dispersing at least one pigment comprising the following steps: contacting an aqueous solution containing at least one pigment with the polymeric dispersant copolymers as described herein.

Tri-substituted aromatic-containing polymeric dispersants

Disclosed are novel tri-substituted aromatic-alkoxylated surface active compounds. Also provided is a method of preparing an aqueous coating composition such as a latex paint including the above components.

Tri-substituted aromatic-containing additives and surfactants and methods for use

A coalescent composition for coating compositions such as paints, adhesives, and coatings comprising a blend of dibasic esters, specifically (i) esters of adipic, glutaric, and/or succinic diacids and/or (ii) esters of isomers of adipic acid have advantages, including efficiency and low VOC.

Low VOC coalescing agents

A coalescent composition for coating compositions such as paints, adhesives, and coatings comprising a blend of diesters, the blend comprising adducts of alcohol and diacids, the alcohol selected from the group consisting of ethyl, propyl, isopropyl alcohol and mixtures thereof, and the diacids selected from the group consisting of a blend of adipic, glutaric and succinic diacids ('AGS') and a blend of adipic, methylglutaric, and ethylsuccinic diacids ('MGA'), and paint, adhesive, and coating compositions comprising such coalescent compositions are disclosed.
