| description | Un método para preparar un polifosfonato ramificado moldeable que comprende: calentar una mezcla de un catalizador de polimerización de fosfonio eliminable, una cantidad de uno o más éster(es)diarílico(s) del ácido fosfónico y un bisfenol en un recipiente a presión reducida de manera que un compuestohidroxiaromático generado mediante la reacción y al menos una parte del catalizador de polimerización se eliminanmediante el calentamiento y la presión reducida; y mediante lo cual se forma el polifosfonato ramificado moldeable.
Disclosed are branched polyphosphonates produced using a polycondensation process, that result in polyphosphonates having Tg of at least 100°C, and which can be further processed to have improved hydro lytic stability compared to other polyphosphonates. The method and polyphosphonate compositions may be made from readily available starting materials providing lower cost fire retardant materials. Also disclosed are polymer compositions that comprise these branched polyphosphonates and at least one other polymer, wherein the resulting polymer compositions exhibit flame retardant properties. |
