Abstract:

In this study, high⁃flowing and high⁃impact polystyrene (FHIPS) was prepared through a continuous bulk polymerization process. The effect of the addition amount of mineral oil on the melt flow rate and mechanical properties of the as⁃prepared FHIPS was investigated, and its microscopic and macroscopic properties were comparatively studied with those of foreign standard products. The results indicated that the melt flow rate of FHIPS gradually increased with an increase in the addition amount of mineral oil. Compared to the similar foreign product of FHIPS (HIPS425TVL), the FHIPS prepared in this work exhibited the same physical properties along with a higher melt flow index.

Key words: high?impact polystyrene, high?flowing polystyrene, polybutadiene rubber, continuous bulk polymerization process
