TRIAZINE-BASED POLYMERS .2. SYNTHESIS AND CHARACTERIZATION OF POLYETHERS

Triazine-based polyethers can be synthesized by phase transfer catalysed interfacial polycondensation at room temperature and reaction times of about 1 to 3 h. In this way, more than 20 polyethers were synthesized and solubilities, glass transition temperatures, thermogravimetric data, elongations at break, tensile strengths, elasticity moduli and impact strengths were determined. In addition, the degree of crystallinity was investigated for the polymer obtained from of 2,4-dichloro-6-diethylamino-s-triazine and bisphenol A by wide angle X-ray diffraction. The increment of the 1,3,5-triazinetriyl ring was determined, which made it possible to calculate the glass transition temperatures of some polyethers according to van Krevelen.
