Problems solved by technology

However, pure PPO resin has a high glass transition temperature, poor melt fluidity, and difficult molding and processing. It needs to be processed at a high temperature of 300°C, which greatly limits its application range.
In order to overcome the shortcomings of PPO and expand its application field, PPO can be modified by blending high-impact polystyrene (HIPS) to improve its molding performance and make it more widely used. However, the existing PPO / HIPS system It is still difficult to obtain PPO / HIPS compositions with good processability and mechanical properties

Description

technical field [0001] The invention relates to the field of materials, in particular to a polyphenylene ether / high impact polystyrene composition and a preparation method thereof. Background technique [0002] Polyphenylene ether resin (PPO) has the advantages of excellent mechanical properties, heat resistance, electrical insulation and low creep at high temperature, while PPO has low density and hygroscopicity, high strength and good dimensional stability . However, pure PPO resin has a high glass transition temperature, poor melt fluidity, and difficult molding and processing. It needs to be processed at a high temperature of 300°C, which greatly limits its application range. In order to overcome the shortcomings of PPO and expand its application field, PPO can be modified by blending high-impact polystyrene (HIPS) to improve its molding performance and make it more widely used. However, the existing PPO / HIPS system It is still difficult to obtain PPO / HIPS compositions...
