    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.
