摘要

Much work has been reported about the deformation of a dispersed single droplet under the flow field of another continuous phase. This investigation has a great significance upon the dispersion or mixing of the multiphase polymer blends. Similar to this, the deformation of a single gas bubble under polymer melt flow field is also well worth studying since its importance upon the dispersion or breakup of bubbles. To obtain the rules of bubble deformation when gas is injected into polymer melt flow field, a series of experiments were made through changing the gas injection pressures. It was found that bubble shapes for the different time periods were changed greatly since its dilatation and the effects of the flow fields. Moreover, the deformation of bubble was severely affected by its volume. Therefore, several different bubble deformation processes were characterized.
