In order to reduce the internal stress in a cured epoxy resin, submicrometer‐sized poly(butyl acrylate) (PBA)/poly(methyl methacrylate) (PMMA) core‐shell particles having cross‐links were dispersed in the resin prior to curing. For the introduction of cross‐links, monoethylene glycol dimethacrylate or glycidyl methacrylate monomer was copolymerized. Cross‐links in the PBA core reduced the shrinkage of the cured epoxy resin, and cross‐links at the PMMA shell produced a strong interaction with the epoxy matrix. The internal stress was reduced effectively by the introduction of cross‐links.
