In the present work, blends between poly(methyl methacrylate) (PMMA) and poly(ethylene‐ co ‐vinyl acetate) (EVA) rubbers obtained by in situ polymerization of the acrylic monomer in the presence of the rubber have been investigated by linear elastic fracture mechanics (LEFM), by Charpy impact tests, and by scanning electron microscopy (SEM). Particularly, a correlation among molecular weight and composition of the EVA rubbers, phase structure development, and, consequently, mechanical impact properties of the resulting blends has been drawn.
