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 1,3,5triazinetriyl ring was determined, which made it possible to calculate the glass transition temperatures of some polyethers according to van Krevelen. ZUSAMMENFASSUNGPolyether auf Triazinbasis kiinnen mittels phasentransferkatalysierter Polykondensation bei Raumtemperatur und Reaktionszeiten von 1 bis 3 h hergestellt werden. Von mehr als 20 Polyethern wurden Liislichkeiten, Glasiibergangstemperaturen, thermogravimetrische Daten, ReiBdehnungen, Reiofestigkeiten, Elastizitatsmoduli und Schlagzahigkeiten bestimmt. Von den Polymeren aus 2,4-Dichlor-6-diethylamino-s-triazin und Bisphenol A wurde zusatzlich der Kristallisationsgrad mittels Riintgenweitwinkelstreuung ermittelt. Das Inkrement des 1,3,5-Triazintriylrings wurde bestimmt, so da13 die Glastemperaturen einiger Polyether nach van Krevelen berechnet werden konnten.
