Abstract
The deformation behaviour of core-shell rubber particles in a polymer matrix under tensile strain was studied using small-angle X-ray scatte ring (SAXS) combined with computer simulation of the scattering. The c ore-shell rubber particles first undergo inhomogeneous deformation, fo llowed by a progressive debonding at the rubber/poly(methyl methacryla te) (PMMA) interfaces beyond the yield point. A dilatation band of cav itated rubber particles, with a tilt angle of 46-48 degrees, is also o bserved in samples with a high rubber particle concentration.
