Multicomponent spatially crosslinked polymers based on ultraphosphates with a glass transition temperature of 123 - 302 ° C have been synthesized. Their hydrolytic stability (the rate of weight loss during boiling in water) was measured, equal to 0.0075 - 0.123 g / min. A correlation has been shown between the glass transition temperature of polymers and their water resistance. A quantitative relationship has been obtained between the pour point and glass transition temperature of polymers t T = t s + (25 ? 35) ° C. It is shown that it is possible in principle to obtain, based on polymer ultraphosphates, highly heat-resistant inorganic thermoplastics with a pour point varying over a wide range.
