Polymer blends have provided an efficient way to fill new requirements for material properties. But owing to the inherent thermodynamic incompatibility, most of polymer blends are phase-separated along the interphases. Recently, to improve compatibilizing effect, it has been directed towards in-situ compatibilization by the reactive processing. It is well established that in the reactive compatibilization the amount of the functional group is very important to determine the morphology and mechanical properties. Until recently, the molecular architecture of reactive compatibilizers is under the control of sorts of functional groups (epoxy, acid, anhydride, oxazoline, isocyanate, carbamate) and concentration of functionality. In addition, so far research on the compatibilization through the polymer/clay hybrid of compatibilizer is very limited. In such polymer/clay nanocomposites, the interfacial effect between the silicate layers and matrix polymers is a key factor leading to high stiffness, high modulus and heat resistant composites. In this study, using epoxy functionalized polymer/organic liphophilic silicate (OLS) nanocomposites with intercalation structure as a compatibilizer, we present a novel investigation of reactive compatibilizing characteristics on the immiscible PC/ABS and SAN/LDPE blends. |
