The kinetic investigetion of polycondensation of dichloranhydride of N,N'-ethylene-1,2-bis-saccharin-5-carboxylic acid, dichloranhydride of N,N'-dimethylbenzenesaccharin-5-carboxylic acid, dichloranhydride of N,N'-dimethyl-m-xylylene-a,a'-bis-saccharin-5-carboxylic acid with diphenylolpropane in solution at temperature 130–2000C has been studied. It is established that the greatest degree of completeness of polycondensation reaction (0.82) is reached in a case of dichloranhydride of N,N'-ethylene-1,2-bis-saccharin-5-carboxylic acid at 2000C. The rate constants and activation energy values of polycondensation of the investigated chloranhydrides of disaccharindicarboxylic acids with diphenylpropane have been calculated.

 

Keywords : dichloranhydride of N,N'-ethylene-1,2-bis-saccharin-5-carboxylic acid, polycondensation, diphenylolpropane
