    摘要: Process for passivating polymeric particles to prevent undesirable interaction with the environment. In particular, sputter coating of metal and surface treatment with aqueous solutions are shown to successfully passivate the particles, such as for example, toner particles, and prevent interaction between the particles and the epoxy embedding resin which causes artifacts, observed by transmission electron microscopy (TEM) imaging.

    摘要: Disclosed is a process for preparing a compound of the formula wherein R1 and R1′, R2 and R2′, and R3 are as defined herein, said process comprising (I) reacting a diacid of the formula HOOC—R2—COOH with a diamine of the formula H2N—R3—NH2 to form an acid-terminated oligoamide intermediate of the formula HOOC—R2—CONH—R3—HNCO—R2′—COOH; and (II) reacting the acid-terminated oligoamide intermediate with a monoalcohol of the formula R1—OH in the presence of a tin or organic titanate catalyst, in the absence of a coupling agent, and in the absence of a solvent to form the product. Also disclosed is a composition prepared by the process.
