The Microphase Separated Structure Formed in the PA6/PP-g-(GMA-co-St) Reactive Blend System

Abstract

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.
