Dicarboxylic acid amide esters diols

High boiling polar compounds, diols, phenols, methyl esters of. dicarboxylic acids, amines, diamines, ethanolamines, amides, aldehydes and ketones. 

Just as simple esters and amides can be made by condensation reactions, polyesters such as Dacron and Mylar are made by reacting diols with dicarboxylic acids (Figure 13.15 A). Similarly, polyamides such as nylon form from amines and carboxylic acids. Starting from anhydrides and amines, polyimides can be formed. These structures tend to be extremely stable, and so are valuable in high temperature applications. 

The chemical resistance of polyester amide glass fibre composite is excellent [126]. A solvent mixture of CF3COOH/CHCI3 was used as a solvent for thermotropic LC polyester, based on 4-chlorocarbonyl phenyl esters of aromatic dicarboxylic acids and phenols or aliphatic diols for viscosity measurement. This indicates thermal stability in various organic solvents. [127]. Unsaturated aromatic LC polyesters, synthesized with the aim to fix the LC state, can be crosslinked by using styrene. The crosslinked matrix can be degraded by refluxing in 3 M aqueous sodium hydroxide solution and methanol in a vol. ratio of 3 2 [128].

Known examples of slip agents useful in photographic materials include polyor-ganosiloxanes, higher aliphatic amides, higher aliphatic esters, metallic salts of higher aliphatic acid, and polyester compounds made of dicarboxylic acid having up to 10 carbon atoms and aliphatic or cyclic aliphatic diol. ...
