Abstract

11-(2-Bromo-2-methyl)propionyloxyundecyl trichlorosilane atom transfer radical polymn. (ATRP) initiator was covalently attached on montmorillonite clay platelets via silylation reactions. The initiator clay was used to polymerize Bu acrylate (BuA) and Me methacrylate (MMA) on the clay surface. Polymn. was performed in bulk monomer soln. or in DMSO. Polymer modified clay was mixed with a poly(BuA-co-MMA) matrix. Small angle X-ray scattering (SAXS) and transmission electron microscopy (TEM) showed that clay modified in DMSO gave exfoliated composites when mixed with the matrix copolymer. Mech. properties of the composites were studied by dynamic mech. thermal anal. (DMTA). The results showed that the mech. properties were improved as a function of clay content, as well with an increasing homogeneity of the nanocomposite. © 2009 Wiley Periodicals, Inc.
