PPE/PA系ポリマーアロイのモルフォロジーと物性

抄録

PPE/PA polymer alloy is industrially manufactured by blending the three components of PPE, PA and elastomer in an extruder. It is well known that the properties of the alloy are greatly affected by not only by the type of polymers, but also their morphology.
In this study, we report morphological changes in the mixing process, and we also report a relationship between the final morphology and mixing conditions. The domain size of the PPE phase and the morphology of the elastomer strongly depend upon the degree of mixing and the styrene content of the elastomer.
The impact strength of the alloy can be closely correlated with the domain size.
