The kinetics of polycondensation reactions might be expected to be similar to those found in condensation reactions of small molecules (evidence suggests that rate coefficients are independent of polymer size). Polyesterification reactions between dibasic carboxylic acids and glycols can be catalysed by strong acids. In the absence of added catalyst, it has been suggested that the acidic monomer should act as a catalyst, whereupon the rate of reaction should be given by...

The first period of scientific work upon returning to Odessa was devoted to study of stereoisomerism of dibasic carboxylic acids, resulting in the discovery of the known Hell-Volgard-Zelinsky method of a-bromi-nation of fatty acids.

To a considerable extent, pyrolysis of nylons made from a diamine and a dibasic carboxylic acid generate the same type of compounds as poly(amino acids). It includes... 

Carbon dioxide also is generated during the pyrolysis of diamine/dibasic carboxylic acid polymers, and its levei is significantly higher compared to that produced in the pyrolysis of poly(amino acids). Several mechanisms can explain the formation of CO2. One of the possibilities involves the formation of water during pyrolysis, which leads to an acid that is decarboxylated as shown in the following reactions ...

Polythioesters have been prepared by the condensation of dimercaptans with either dicarboxylic acids or ester derivatives [12,13], the ester interchange of phenyl esters of dicarboxylic acids [14], or by their reaction with acid chlorides of dibasic carboxylic acids [15,16]...

Upon heating with acetic anhydride, dibasic carboxylic acids lead to cyclic anhydrides of ring size 6 or smaller. Diacids longer than glutaric acid lead to cyclic ketones (eq 19). ... 

Dipole moments of (p-RCeHJAsYa (Y = C1 or OR ) were measured changes in R (R = N02, Br, H, or Me) influenced neither the dipole moment of the Caryl—As(OR)2 Unit nor the conformation. Dibasic carboxylic acids, e.g., malonic and oxalic, cleave two Ph-Bi bonds in PhgBi.
