DEFINITION

Classification: 526/344.2

Polymerization of vinyl chloride only in an aqueous medium:

(under subclass 344) Subject matter wherein vinyl chloride only is polymerized under conditions wherein an aqueous medium (water)is employed in the process and products which are the result of such polymerization process.

(1) Note. This subclass is intended to take those processes and products 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.).
