    摘要: New polyamides are prepared by reacting (A) a dibasic acid ester of the formula R2OOC-CH2-CH2- R1-CH2-CH2-COOR2 wherein R1 represents a bivalent vinylidene-type radical having one double bond and R2 represents a radical which forms with acrylic acid an ester, or the dibasic acid (R2 is H) obtained by hydrolysis of the above ester, or the saturated dibasic acid obtained by hydrogenation of the above acid or an ester of the above saturated dibasic acid, said dibasic acid ester being obtained from an acrylic acid ester and a vinylidene type olefin of the formula

    (where R4 and R5 represent H or an alkyl group having 1 to 19 carbon atoms) with (B) a diamine of the formula H2N-R3-NH2 wherein R3 represents an aliphatic, aromatic or alicyclic hydrocarbon having 1 to 10 carbon atoms.
