METHODS OF MAKING DISPERSIBLE ADDITIVES FOR POLYMERIC MATERIALS |
摘要 |
Additives for polymeric compositions are prepared by coated a pigments with a dispersant, and thereafter dispersing the dispersant-coated pigment in a liquid nonaqueous polymeric carrier. Preferably, the dispersant-coated pigment is spraydried. That is, most preferably, an aqueous dispersion of the pigment and dispersant is subjected to a spray-drying operation so as to obtain pigment coated with the dispersant. The dispersant-coated pigment has an average particle size of about 5 .mu.m or greater, but is capable of breaking apart to average particle sizes of about 1 .mu.m or less when dispersed in a polymeric host material.
