Adhesion between filler and matrix has been studied using a model system composed of glass bead filled poly(vinyl chloride) (PVC). Stress-strain and volume-strain tests and scanning electron microscopy revealed that adhesion is improved by grafting poly(methyl methacrylate) (PMMA), which is known to be miscible with the PVC matrix, upon the surface of the glass beads. The best results were obtained when large amounts of grafted PMMA were used, leading to maximum stress of the composite, nearly as high as that of pure PVC.
