DEFINITION

Classification: 523/335

Creaming, agglomerating, or coalescing a solid polymer latex or aqueous dispersion wherein solid polymer latex or aqueous dispersion is the result:

(under subclass 1) Process wherein an aqueous dispersion or latex of a solid polymer is treated by a step of creaming, agglomerating, or coalescing which step does not destroy the latex or aqueous dispersion.

(1) Note. Creaming relates to separation of a latex into a cream layer having most of the dispersed solid polymer and a layer having most of the aqueous components of the latex; however, the cream layer remains a latex or aqueous dispersion.

(2) Note. Agglomerating or coalescing refers to regulation of the particle size of the dispersed solid polymer particles in the latex.

(3) Note. The creamed, agglomerated, or coalesced latex, dispersion or suspension can be coagulated, broken, or otherwise destroyed in a later step.
