    • Disclosed is a process for preparing a compound of the formula wherein R1 is an alkyl group having at least one ethylenic unsaturation, an arylalkyl group having at least one ethylenic unsaturation, or an alkylaryl group having at least one ethylenic unsaturation, R2 and R3 each, independently of the others, are alkylene groups, arylene groups, arylalkylene groups, or alkylarylene groups, and n is an integer representing the number of repeat amide units and is at least 1, said process comprising: (a) reacting a diacid of the formula HOOC—R2—COOH with a diamine of the formula in the absence of a solvent while removing water from the reaction mixture to form an acid-terminated oligoamide intermediate; and (b) reacting the acid-terminated oligoamide intermediate with a monoalcohol of the formula R1—OH in the presence of a coupling agent and a catalyst to form the product.
    • 公开了一种制备下式化合物的方法,其中R 1是具有至少一个烯属不饱和键的烷基,具有至少一个烯属不饱和键的芳基烷基或具有至少一个烯属不饱和键的烷基芳基 烯键式不饱和键,R 2和R 3各自独立地为亚烷基,亚芳基,芳基亚烷基或烷基亚芳基,n为代表 重复酰胺单元的数目并且至少为1,所述方法包括:(a)使式Ⅳ的二酸与-in-line-formula description =“In-Line Formulas”end =“lead”→> HOOC-R' 在不存在溶剂的情况下,在从反应混合物中除去水的情况下,使用下式所示的二胺,在线式描述=“In-line Formula”中, 以形成酸封端的低聚酰胺中间体; 和(b)使酸封端的低聚酰胺中间体与下式的一元醇反应:式中:=“引入”→R 1 -OH 在偶联剂和催化剂的存在下,<?in-line-formula description =“In-line formula”end =“tail”?>以形成产物。
