Modification of epoxy-4,4′-isopropylidenediphenol resins with phosphorylated methacrylates for preparing compounds of the interpenetrating polymer network type

Phosphorylated methacrylates were prepared by reaction of butylphosphoric acids and their salts with glycidyl and β-chloroethyl methacrylates. The modifying properties of these substances toward epoxy-4,4′-isopropylidenediphenol resins ED-16 and ED-20 were examined. The physicochemical characteristics and heat resistance of the composites obtained were studied in relation to the structure of methacrylates, curing agent used, formulation, and curing conditions.
