1. Nylon 66 is synthesised by polycondensation of hexamethylenediamine and adipic acid. 2. In a second step polycondensation is done to make nylon TMDT. 3. In manufacturing processes by polycondensation a high purity of the starting materials is important. 4. The average chain length of a particular batch of resin can be controlled during polycondensation . 5. The first time, Smith et al . showed the polycondensation of bisphenols with PFCAs. 6. It is necessary to hold the growing polymer chain in solution in the course of the polycondensation process. 7. Water removal by application of a vacuum or by azeotropic distillation is crucial to favor polycondensation over transesterification. 8. Subsequent thermal treatment ( firing ) may be performed in order to favor further polycondensation and enhance mechanical properties. 9. A Rs57-crore backward integration polycondensation project, which was also to be part funded by ICICI, was put on hold. 10. During surfactant-mediated synthesis, hydrolysis and polycondensation , or co-condensation, are used to fuse precursor molecules in a framework.
