However, polyamides which contain both non-hydrogen-bearing amide groups and hydrogen-bearing amide groups, e. g. a polyamide derived from a dibasic carboxylic acid, a diprimary diamine, and a disecondary di- t3 amine, can be used. The polyamides used in the practice of this invention are ...
which is connected to a carboxyl group on both sides, making it an active group with important application value. Due to the properties of this amino group, it easily reacts with carboxylic acids and activated esters to form stable amide bonds. Moreover, under specific reducing...

22. The expanded foam of claim 21, wherein the cross-linked polymer is the product of an olefinic polymer having pendant carboxylic acid functional groups, pendant hydroxyl functional groups, pendant amino functional groups, pendant amide functional groups, or a combination thereof, with a cross-li...
(II) including carboxyl and salts thereof (III); in addition, the amide compound (I) including carboxyl is obtained through reacting binary- quaternary polybasic carboxylic acid (i) with primaryaliphaticamine and/ or aliphatic secondary amine (ii-1) having a substituent group with a carbon ...
The method at least two of making carboxylic acid amide substitute catalyst with one Grignard reagentThe invention relates to a method for disubstituting carboxylic acid amides on the geminal carbonyl-C-atom using at least one grignard reagent in the presence of a metal alcoholate compound used ...
(4) rearrangement of Cy-Ph-COCH 3 using sulphur and ammonia or an amine to give a compound in which X is carboxylic acid and R 1 , R 2 are hydrogen or a compound in which X is thioamide and optionally hydrolysing the amide, (5) hydrolysis of acid halide or anhydride or a ...
Alternatively, a corresponding derivative of 1-aminobenzene containing as substituents in the phenyl nucleus the methyl radical and a halogen atom is first acetylated with a haloacetic acid or a derivative thereof, such as a halide, ester, anhydride, amide or ester and the halo-acetylamide so ...
