DEFINITION

Classification: 521/65

Process of forming a cellular product from an aqueous latex, aqueous dispersion, aqueous emulsion containing a solid

polymer; process of preparing a latex, dispersion, or emulsion containing a solid polymer which is designed to be formed into a cellular product, or composition thereof:

(under subclass 50) Subject matter wherein a cellular product is produced from an aqueous latex, aqueous dispersion, or aqueous emulsion containing a solid polymer.

(1) Note. This subclass provides (1) for processes of forming a cellular product from an aqueous latex, aqueous emulsion, or aqueous dispersion containing a solid polymer; (2) for an aqueous latex, aqueous dispersion, or aqueous emulsion, of a preformed solid polymer which is claimed as being capable of preparing a cellular product; or (3) for processes of preparing an aqueous latex, aqueous emulsion, or aqueous dispersion which is capable of being formed into a cellular product, e.g., polymerizing a material and forming a polymer containing latex thereby and subsequently treating to form a cellular product, etc.

(2) Note. Excluded from this area are processes involving preparing a latex, emulsion, or dispersion which is destroyed as by coagulation, precipitation or any other manner prior to the cell-forming step.
