ABSTRACT:
A polymer dispersed liquid is prepared by the following steps: (1) polymerzing at least two different types of monomers of the vinyl series in the presence of a block or graft copolymer of the vinyl series containing a component solvating in a dispersion medium (.alpha.) and a component not solvating in the dispersion medium, but being compatible with a dispersed polymer (.beta.) in an organic liquid in which a copolymer of the vinyl series to be produced is soluble; then at that time, uniformly admixing an alkylated melamine-formaldehyde reaction product before, during or after the polymerization, (2) distilling out a part of the organic liquid, thereby varying the solubility parameter of the organic liquid of said polymer solution by more than about 0.5.
