Abstract: An aqueous latex contains a functionalized copolymer prepared by emulsion polymerization. The copolymer can be applied to textile nonwoven materials and to various cellulosic substrates, and when utilized as a binder imparts enhanced properties thereto such as wet tensile strength, low temperature cure rates, and the like. The monomers generally forming the copolymer include at least two functional type monomers, one of which contains an activatable ester group, and at least one latex forming monomer.

Abstract: A process for preparing unsaturated nitrogen containing acids such as acrylamidoglycolic acid utilizes a catalyst free route and low pH conditions. An unsaturated amide such as acrylamide is reacted with an aldehyde acid such as acid in an aqueous environment. The unsaturated nitrogen containing acids are typically produced in solution form and can be utilized as such.

Abstract: This invention relates to the use of bisulfite-terminated oligomers as dispersants for solid particulate matter, i.e., low molecular weight bisulfite-terminated polymers containing carboxylate groups and either cyano or carbomethoxy moieties are improved dispersants for solid particulate matter like pigments such as titanium dioxide, clay, calcium carbonate, talc, and zinc oxide, as well as for organic pigments. Particularly, these dispersants have been found useful for stabilizing paper coating compositions.

Abstract: Polymer latex (e.g., butadiene-styrene-itaconic acid copolymer latex) resulting from aqueous emulsion polymerization in the presence of conventional anionic emulsifying agent (e.g., dodecyl benzene sulfonate) has increased particle size and improved stability if a lignosulfonate salt (e.g., sodium lignosulfonate) is further employed as an emulsion modifier in the emulsion polymerization process. The resulting latex is useful for carpet scrim application.
