Synthesis and characterization of a water-soluble nylon copolyamide

A novel water-soluble copolyamide based on Nylon 66 was synthesized via solution-melt polycondensation of hexanedioic acid and sodium 5-sulfoisophthalate with 1,6-diaminohexane. The chemical structures of the products were ascertained by various spectroscopic techniques (FT-IR, Raman, and 1H NMR). The thermal properties of the polyamides under consideration were measured by TGA and DSC. According to the temperature dependence of FTIR spectra, it was found that the average strength of the intermolecular hydrogen bond of the water-soluble copolyamides becomes weak with increasing the temperature. It was found that the obtained random copolyamides could self-assemble into spherical micelles in aqueous solution with the size dependent on the hydrophilic fraction according to the DLS and TEM measurements.

Semifluorinated acid halides and fluorinated polymers produced therefrom

Compounds having the formula F(CF2)q-(CH2)p-1-COX' wherein q ranges from 6-15, p ranges from 3-15 and X' is halogen are useful as reactants for hydroxylated block copolymers or polyamines to produce fluorinated polymers.

Manufacture of a highly concentrated aqueous solution of a dicarboxylic acid diamine salt and a nylon precondensate

A process for the manufacture of a highly concentrated aqueous solution of a salt of a dicarboxylic acid and a diamine, as well as of a nylon precondensate, by reacting an alkanedicarboxylic acid of 6 to 12 carbon atoms and a diamine of the formula NH2 RNH2, where R is alkylene of 6 to 12 carbon atoms or is STR1 An aqueous solution, of lower concentration, of a salt of a dicarboxylic acid and a diamine, containing an appropriate dissolved excess of the particular dicarboxylic acid, is reacted with the particular diamine in the molten state, in an equivalent amount to the dissolved dicarboxylic acid, the reaction being carried out under superatmospheric pressure and the final reaction temperature being kept at from 140° to 210° C. The solution obtained is used for the manufacture of a nylon.
