Abstract: 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.

Abstract: A discrete nanostructure formed by a method comprising providing an aliphatic multi-block copolymer. The aliphatic multi-block copolymer includes at least one polyester block and at least one functionalized polycarbonate block. The aliphatic multi-block copolymer, a deprotonating agent and water are mixed to form an aqueous mixture. The aqueous mixture is maintained at a reaction temperature suitable to result in self-assembly of the multi-block copolymer into nanoparticles.
