Novel thermoset materials of improved impact, strength and fatigue properties are prepared from an alpha-beta olefinically unsaturated copolymer of vinyl monomers and a crosslinking amount of particulate graded-rubber having alpha-beta olefinicunsaturation surface functionality. The graded-rubber particles have a rubbery core and a glass-like polymeric shell.
