“…Isocyanates will copolymerize with aldehydes such as acetaldehyde [13] and chloral [14][15][16]. IR analysis of such copolymers shows the presence of structures such as indicating that the nitrogen-carbon double bond opens as in the homopolymerization [15].…”

By polycondensation of triglyceride of saccharin-6-carboxylic acid with some aliphatic diamines, the thermal-stable super-branched polyestersulfoimides – polyglycerides of saccharin-6-carboxylic acid have been obtained. The structures of the synthesized compounds have been confirmed by data of the IR spectroscopy. The yield of the purposeful product was 80–83%. It has been found that the synthesized polyglycerides are well dissolved in polar aprotonic solvents. The thermal stability of the obtained compounds was studied by a method of differential-thermal analysis on derivatograph of system ʺPaulik-Paulik-Erdeyʺ. The derivatographic investigations showed that the synthesized polyglycerides have high thermal stability, decreasing with the growth of length of the aliphatic fragment in their composition. For comparative estimation of the thermal and physical-mechanical indices of the synthesized polyglycerides, the corresponding indices of the industrial polyesterimide Zellamid 1000 have been also given. It has been found that the obtained polyglycerides do not concede to industrial polyesterimides on physical-mechanical indices, but exceed them on thermal stability

Homo‐ and copolymers derived from mono‐ and diisocyanates are treated in this article. Also, addition, condensation, and addition/condensation polymers derived from diisocyanates are included. Of commercial interest are segmented block copolyamide elastomers produced from methylene di‐ p ‐phenylene isocyanate (MDI) and macrodicarboxylic acids and dicarboxylic acids. This reaction polymerization is conducted in a vented extruder or in solution. Also, engineering plastics are obtained from diisocyanates and dicarboxylic acids. Poly(amide imides) and poly(imides) are produced from MDI and TDI (toluene diisocyanate) and trimellitic acid anhydride and isophthalic acid and dianhydrides, respectively. Heterocyclic polymers with useful high temperature properties made from MDI and suitable monomers by a polyaddition/condensation reaction are also included.
