This invention relates to a composition comprising a particulate polymer dispersed in a continuous phase and a process for preparing the particulate polymer. The particulate polymer is characterized in that it is prepared by contacting a polyamine with a carbonyl-containing compound. The particulate polymer dispersions can be used for preparing reinforced polymer matrices, especially where the matrix comprises urethane and/or urea linkages. The invention allows for the preparation of a particula...

This invention relates to unique and novel polymer complexes between a metal neutralized sulfonated polymer and a tertiary amine terminated polylactone composition. The resulting polymer complexes have a variety of uses including those as diverse as adhesive agents, thermoplastic elastomers, additive uses wherein these materials can be utilized to compatibilize two different polymers which are normally incompatible. These polymer complexes can also be blended with fillers and/or oils when the su...

The present invention provides a polymer derived from a cellulosic, lignocellulosic, or polysaccharide material having superabsorbent properties. Methods for making the polymer and personal care absorbent products that incorporated the polymer are also provided.

Disclosed is a process for controlling the level of in-process monomer in an emulsion polymerization reaction. Also disclosed is a method of controlling particle size by controlling the level of in-process monomer.

Coatings, particularly thin films, of polymeric material are produced in accordance with the invention by applying a finely divided aerosol of polymer solution to a substrate and substantially simultaneously applying an energy source to the applied solution to apply the solution. In cases where the polymer is cross-linking, the energy source assists in cross-linking of the polymer. The preferred energy source is a flame that may optionally or desirably deposit material along with the polymer spr...
