DEFINITION

Classification: 526/340.1

Polymerized in the presence of a water medium:

(under subclass 335) Subject matter wherein a hydrocarbon monomer containing two or more ethylenic groups is polymerized under conditions wherein an aqueous medium (water)is employed in the process or products which are the result of such a polymerization process.

(1) Note. This subclass is intended to take those processes or products thereof, wherein a significant amount of water is employed (emulsion, suspension, etc.) rather than where mere trace amounts of water are utilized (e.g., ppm H2O, etc.).
