  • Patent number: 5198510
    Abstract: Vinyl ester resins of the type already having reactive liquid polymers reacted into the backbone of the resins, are cured in the presence of a reactive liquid polymer additive admixed with the prereacted vinyl ester resin. Heating of the system during cure causes the reactive liquid polymer additive to miscibilize with the vinyl ester base resin. The vinyl ester resin modified in the manner described above shows a significant enhancement in toughness as measured by fracture energy over unmodified counterparts or counterparts modified by known methods of adduction or admixing alone.
