The dependence of the fracture behavior of photocured dimethacrylate-based composite resins on the matrix crosslink density (varied by postcuring at various temperatures) was investigated. In general, the fracture toughness (KIc) was increased by postcuring as has been observed for epoxy-amine netwo
## Abstract **Summary:** Linseed oil was derivitized with 1,3βbutadiene via a DielsβAlder reaction. The cycloaddition adduct was then epoxidized using a hydrogen peroxide/quaternary ammonium tetrakis(diperoxotungsto) phosphate system. The cyclohexene derivitized linseed oil (CLO) and the epoxidized
