摘要：
A process of making a pigmented shaped article comprising: (a) providing polytrimethylene terephthalate chips and two or more colored pigmented chips each containing at least one different color pigment; (b) heating the polytrimethylene terephthalate chips and colored pigmented chips to a temperature of about 200-about 280° C. to melt the chips and form a polymer composition comprising the polytrimethylene terephthalate and at least one color pigment; and (c) forming a shaped article from the polymer composition.
