摘要:
A nonlimiting example method for synthesizing a pigment-pendent polyamide (PP-polyamide) may comprise: functionalizing metal oxide particles bound to a pigment particle with a compound having an epoxy to produce a surface treated pigment having a pendent epoxy; and reacting the pendent epoxy with a polyamide to yield the PP-polyamide. Another nonlimiting example method for synthesizing a PP-polyamide may comprise: functionalizing metal oxide particles bound to a pigment particle with a silica particle having a carboxylic acid surface treatment to produce a surface treated pigment having a pendent carboxylic acid; converting the pendent carboxylic acid to a pendent acid chloride; and reacting the pendent acid chloride with a polyamide to yield the PP-polyamide. Said PP-polyamide may be useful in producing objects by methods that include melt extrusion, injection molding, compression molding, melt spinning, melt emulsification, spray drying, cryogenic milling, freeze drying polymer dispersions, and precipitation of polymer dispersions.
