摘要: 近年来,有关高聚物微相分离结构的研究不断深入,发现了许多新的微相分离形态.但这些研究几乎全部集中在嵌段或接枝共聚物上,即共聚物本身具有的链结构导致了微相分离结构.

Abstract: In this paper, the phase morphology of the PA6/PP-g-(GMA-co-St) blends was investigated by means of transmission electron microscopy(TEM). The uniform and fine dispersed phase was observed. The size of the dispersed phase was less than 0.5 μm. It was also found that the microphase separated structure formed in the blends. FTIR spectra revealed that the PP-PA6 graft copolymers formed in situ by chemical reactions occurred between epoxy groups of PP-g-(GMA-co-St) and the terminal amino or carboxylic groups of PA6 during the melt mixing. The formation of the microphase separated structure should be related to the in situ formed PP-PA6 graft copolymer.
