DEFINITION

Classification: 524/458

Polymerizing in the presence of water and in the presence of a solid polymer derived from ethylenic reactants only:

(under subclass 457) Subject matter wherein water is a nonreactive material present during said polymerization and the said preformed solid polymer is from ethylenically unsaturated monomers only.
