Method for producing colored and exactly spherical fine-grains of polymer |
摘要 |
A method for producing colored and exactly spherical fine-grains of polymer by carrying out the suspension and polymerization of ethylenic unsaturated monomers containing a pigment in water under the presence of a suspension stabilizer, wherein an inorganic pigment treated with silane-coupling agent is used as said pigment. According to the present invention, the pigments are homogeneously dispersed in said exactly spherical fine-grains of polymer and a loss of color is prevented.
