[0025] (1) Preparation of borate esters with dual active functional groups

[0026] Add 100 parts of boric acid and 50 parts of gluconic acid into a three-necked glass flask with a stirrer, thermometer and water separation and reflux device, and add 10 parts of toluene as a solvent, heat in an oil bath, and stir the reaction at 90 ° C. Toluene and The water generated by the reaction forms an azeotrope and gradually evaporates, and the generated water is separated through the water separation and reflux device. After reacting for 8 hours, distill under reduced pressure at 88 kPa for 40 minutes to remove the remaining toluene, a small amount of water and excess polyhydric acid. Carboxylic acid or its derivatives are used to obtain borate ester products with dual active functional groups, which are sealed and dried.

Abstract

The invention relates to a compatilizer, an application of the compatilizer in a polyphenyleneoxide/nylon alloy and a preparation method of the polyphenyleneoxide/nylon alloy. The compatilizer provided by the invention is boronic acid ester prepared from boronic acid and substances containing hydroxy groups and carboxyl groups, can be directly used for preparing the polyphenyleneoxide/nylon alloy, and also can be subjected to melt extrusion with polyphenyleneoxide to be prepared into a polyphenyleneoxide blending compatibilization system which is used for preparing the polyphenyleneoxide/nylon alloy. The preparation method of the polyphenyleneoxide/nylon alloy is implemented as follows: drying and evenly stirring the compatilizer or the polyphenyleneoxide blending compatibilization system, polyphenyleneoxide and nylon; and feeding the mixture in a double screw extruder for extrusion to obtain the compatibilization modified polyphenyleneoxide/nylon alloy, wherein the screw temperature is 170-295 DEG C and the screw revolving speed is 70-120 revolutions/minute. The invention has the advantages of being convenient in processing, having simple process, notable compatibilization effect, remarkably improved tensile property and bending property, favorable and stable comprehensive property and wide industrial application prospect, and satisfying strength requirements of common applications.

Description

technical field [0001] The invention relates to a compatibilizer, the application of the compatibilizer in polyphenylene ether / nylon alloy and the preparation method of the alloy. Background technique [0002] Polyphenylene oxide (PPO) is an amorphous polymer obtained by polymerization of 2,6-dimethylphenol through oxidative coupling. It is a high heat-resistant engineering plastic with good creep resistance. , at 23°C and 14MPa load, the creep value after 300 hours is less than 0.5%, and the creep value changes little with the increase of temperature. However, it has high brittleness, poor processability and solvent resistance, its melting temperature is 262-267°C, and its melt viscosity is very high below 300°C, making it impossible to process and shape, which limits its application range. For this reason, it is necessary to realize its wide industrial application through alloying or compound modification. [0003] Nylon (Polyamide, referred to as PA) is a tough angular ...
