Problems solved by technology

[0007] At present, although there are many different PPO / PS alloys, they still cannot meet the needs of different fields. People have higher and higher requirements for product performance, and require products with good overall performance. For example, some electrical products require materials with high rigidity. Good heat resistance, good dimensional stability and good flame retardancy, etc., but the existing materials are not ideal, and the performance of the material needs to be further improved to meet the requirements of the product

Description

technical field [0001] The invention relates to a polyphenylene ether composition and its application, belonging to the field of polymer alloys. Background technique [0002] Polyphenylene ether (PPO) has excellent mechanical properties and electrical properties, but its high melt viscosity and poor fluidity make it difficult to process and shape, so it is generally used in various modified varieties, such as PPO and PS, PP Polyphenylene ether alloys such as polyphenylene ether or PA have been widely used, and the performance and use value of the blended modified polyphenylene ether far exceed its own performance and use value. [0003] Application No. 02100364.5 discloses a reactive, environmentally friendly flame-retardant high-gloss polyphenylene ether compound and its preparation method. The composition (parts by weight) of the compound is: 100 parts of polyphenylene ether, 30- 300 parts, 6-40 parts of environmentally friendly main flame retardant, 3-20 parts of auxilia...
