The synergetic effect of a reactive compatibilizer and organo-montmorillonite (OMMT) on phase morphology and properties of polyamide 6 (PA6)/polydimethylsilicone (PDMS) blend with a high viscosity ratio of dispersed phase and matrix was studied. A small amount of an amine-terminated copolymer of polyether amine (PEA) and PDMS (PDMS-b-PEA) as a reactive compatibilizer can significantly decrease the dispersed phase domain size. However, the dispersed phase domain size has still been above 2 μm even when the PDMS-b-PEA concentration reaches 5 wt %. OMMT as the second additive can further dramatically decrease the dispersed phase domain size due to the barrier effect for effectively preventing the coalescence of the dispersed phase domain. Moreover, the presence of PDMS-b-PEA can promote the uniform dispersion of OMMT. The synergetic effect of PDMS-b-PEA and OMMT can also improve tensile properties and decrease water absorption.

反应性增容剂和有机蒙脱土对高粘度比聚酰胺6 /聚二甲基硅氧烷共混物分散的协同作用

研究了反应性增容剂和有机蒙脱土（OMMT）对分散相和基体高粘度比的聚酰胺6（PA6）/聚二甲基硅氧烷（PDMS）共混物的相形态和性能的协同作用。少量的聚醚胺（PEA）和PDMS（PDMS- b -PEA）的胺封端共聚物可作为反应性增容剂，可显着减小分散相的畴尺寸。然而，即使当PDMS- b- PEA浓度达到5wt％时，分散相域尺寸仍保持在2μm以上。由于有效地防止了分散相域的合并的阻挡作用，作为第二添加剂的OMMT可以进一步显着减小分散相域的尺寸。此外，PDMS- b的存在-PEA可以促进OMMT的均匀分散。PDMS- b- PEA和OMMT的协同作用还可以改善拉伸性能并降低吸水率。
