Description

technical field

[0001] The invention relates to a polymer compound composition containing polystyrene and polyphenylene ether, especially a halogen-free flame-retardant high-impact polystyrene (HIPS) composite material with high fluidity and a preparation method thereof. Background technique

[0002] The chemical name of polyphenylene oxide (PPO) is poly-2,6-dimethyl-1,4-phenylene ether, which is an amorphous resin with a glass transition temperature as high as 220°C. It has poor melt fluidity, difficult molding, and high price. Application is limited. In 1967, General Electric Company of the United States successfully developed a modified PPO (nIP1) named Noryl through alloying with polystyrene (PS), especially high-impact polystyrene (HIPS), which has great processing performance. In order to improve, and basically retain the original characteristics of pure PPO. MPPO is modified polyphenylene ether, which has the lowest relative density among general engineering plastic...
