    摘要： A method of making a pure block copolymer includes forming a crude block copolymer; heating a solution of the crude block copolymer and alcohol; and cooling the solution to promote precipitation of a purified block copolymer, wherein an amount of impurities remaining in the purified block copolymer is from about 0 to about 5 wt % based on a total weight of the purified block copolymer; a ratio of a polydispersity index of the crude block copolymer to a polydispersity index of the purified block copolymer is from about 1.02 to about 1.25; a ratio of a molecular weight of the crude block copolymer to a molecular weight of the purified block copolymer is from about 0.75 to about 1.0; and a ratio of a number average molecular weight of the crude block copolymer to a number average molecular weight of the purified block copolymer is from about 0.65 to about 1.

    摘要： An emulsion aggregation (EA) toner includes an amorphous polymeric resin, optionally a colorant, and a small molecule crystalline organic compound having molecular weight less than 1,000 g/mol and melting point less than the fusing temperature of the EA toner, wherein a mixture of the resin and the small molecule compound is characterized by a reduction in glass transition temperature from that of the resin and by the lack of a significant solid to liquid phase transition peak for the small molecule compound as determined by differential scanning calorimetry, the enthalpy of fusion for the small molecule compound in the mixture being measured to be less than 10% of the enthalpy of fusion of the compound in pure form. Furthermore, the EA toner may be configured to have a crease fix minimum fusing temperature (MFT) less than or equal to the crease fix MFT of a benchmark ultra-low-melt emulsion aggregation toner.
