A continuous bulk polymerization and esterification process includes continuously charging into a reaction zone at least one ethylenically unsaturated acid-functional monomer and at least one linear or branched chain alkanol having greater than 11 carbon atoms. The process includes maintaining a flow rate through the reaction zone sufficient to provide an average residence time of less than 60 minutes and maintaining a temperature in the reaction zone sufficient to produce a polymeric product incorporating at least some of the alkanol as an ester of the polymerized ethylenically unsaturated acid-functional monomer. The polymeric product is used in various processes to produce water-based compositions including emulsions and dispersions such as oil emulsions, wax dispersions, pigment dispersions, surfactants and coatings which contain the polymeric product. A polymeric surfactant includes at least one ethylenically unsaturated acid-functional monomer which has been radically incorporated into the polymeric surfactant and at least one ester of the incorporated ethylenically unsaturated acid-functional monomer which has a linear or branched chain alkyl group with greater than 11 carbon atoms. The molar critical micelle concentration of the polymeric surfactant is less than 1.0&#xd7;10moles/liter. Aqueous 2 percent solutions of certain polymeric surfactants have a surface tension of less than 45 mN/m at 30&#xb0; C. and exhibit a decrease in surface tension of at least 5 mN/m as the temperature warms from 30&#xb0; C. to 50&#xb0; C.

Continuous bulk polymerization and esterification process

Disclosed herein are starch stabilized polymeric emulsions. Persulfate salts degrade starch to give it suitable characteristics, and then also, essentially simultaneously, initiate polymerization with monomers. This permits a single reaction condition to be used for both the degradation step and the polymerization step, and avoids the need for use of metallic ions such as iron.

Starch degradation/graft polymerization composition, process, and uses

An emulsion polymerization system comprising a polymeric stabilizer, wherein the polymeric stabilizer comprises one or more alpha olefin/maleic anhydride copolymers and is present in the emulsion polymerization system in an amount greater than 0 and less than 5% by weight.
