Embodiment 1

[0058] In a 100mL three-necked flask equipped with a mechanical stirrer, a condenser, a desiccator and an air duct, first heat it to 100°C, fill / discharge nitrogen three times, and add bis(trimethylsilyl)-4,4′-(6-methyl 20mmol of oxy-1,3,5-triazine-2,4-diphenyl)diphenyl ester and 20mmol of hydroquinone were gradually heated from room temperature to 260°C under a nitrogen atmosphere, and the heating temperature interval was 40°C. At each temperature point, the reaction duration was 0.4 h. Control the temperature at 260°C for 4h. The system was vacuumed and decompressed to 80KPa, and the reaction was continued for 3h. After cooling down, add 500mL of methanol as a precipitant. The polymer is crushed, repeatedly washed with deionized water, sucked dry, and vacuum-dried to obtain aryl-1,3,5-triazine polyarylate resin. The resin is light yellow powder;

Abstract

The invention discloses an aryl-1,3,5-triazine polyarylester and a preparation method thereof, and belongs to the technical field of polymer science. The aryl-1,3,5-triazine polyarylester is characterized in that a macromolecular main chain contains a structural unit like the general formula I. The aryl-1,3,5-triazine polyarylester with high molecular weight, excellent thermal stability and good mechanical strength can be conveniently and rapidly prepared with disilyl ester compound disclosed by the invention and commercial aromatic bisphenol monomer as polycondensation monomers and / or other commercial disilyl ester compounds added at the same time as copolycondensation monomers by the step of step-by-step polycondensation in a high-boiling-point inert liquid medium or in a molten / solid phase state. The polyarylester resins can be used in the fields of heat resistance paints, coating, adhesives, separation membranes, composite materials and the like, and have wide application prospects.
