“…The dried polymer was further purified by dissolving it in chloroform and re-precipitated with methanol. The polymer obtain was about 72 % of the theoretical yield [16][17][18][19][20][21][22]. The yield of synthesized polycyanurates varies from 64 to 82 %.…”

“…3,4 Recently, various polyesters and polyamides based on s-triazine derivatives have been synthesized in our laboratory. [5][6][7][8] We have used 2-carbazol-4,6-dichloro-s-triazine (CDCT) as a monomer to explore the experimental conditions for the synthesis of polymers by an interfacial technique. The present investigation should aid in determining suitable reaction conditions, studying the effects of certain specific structural features included in the polymer backbone, investigating the kinetics of the thermal degradation of the polymers synthesized and studying the effect of the chemical structure of diols on the polymers from which they are synthesized.…”

Eight polycyanurates have been synthesized by the interfacial polycondensation of 2-carbazol-4,6-dichloro-s-triazine with 1,7-dihydroxynaphthalene (DHN-1,7), 1,4-dihydroxyanthraquinone (DHA-1,4), ethylene glycol (EG), diethylene glycol (DEG), triethylene glycol (TEG), 1,2-propanediol (Pr-1,2), 1,4-butanediol (Bu-1,4) and 1,8-dihydroxyanthraquinone (DHA-1,8). All of the polycyanurates thus synthesized were characterized for their solubility, density, viscosity, infrared spectra, nuclear magnetic resonance spectra and thermogravimetric analysis. Chlorinated solvents were found to be good solvents for all of the polymers. The density of the polycyanurates varied from 1.186 to 1.247 gm cm À3 . The intrinsic viscosity of the polycyanurates followed the sequence given below: homopolycyanurates of DHN-1,7 (HPDHN-1,7)4homopolycyanurates of DHA-1,8 (HPDHA-1,8)4homopolycyanurates of DHA-1,4 (HPDHA-1,4)4homopolycyanurates of EG (HPEG)4homopolycyanurates of DEG (HPDEG)4homopolycyanurates of TEG (HPTEG)4homopolycyanurates of Bu-1,4 (HPBu-1,4)4homopolycyanurates of Pr-1,2 (HPPr-1,2). The thermal stability of the polycyanurates increased as follows: HPTEGoHPPr-1,2oHPDEGEHPBu-1,4oHPEGoHPDHA-1,8oHPDHA-1,4oHPDHN-1,7.

A new method to prepare low melting point polyamide-6 (LPA6) by complex reaction of calcium chloride (CaCl 2 ) and polyamide-6 (PA6) in a co-rotating twin screw extruder was reported. We employed a new rheological method to study the crystallization behavior of PA6/CaCl 2 complex and the mechanism of confined crystallization of PA6. Compared with differential scanning calorimetry (DSC), this method was more capable of detecting crystalline information. What's more, it was also an effective method for studying mechanism of confined crystallization. From the results of X-ray diffraction, DSC, infrared spectroscopy, rheology, and mechanical properties, the complex reaction of CaCl 2 with the carbonyl oxygen atom in the amide group disrupted the intermolecular hydrogen bonding and confined the mobility of PA6 molecules. This could significantly reduce the crystallinity and melting temperature of PA6, and improve tensile strength and notched Izod impact strength.
