  • Patent number: 5567788
    Abstract: A liquid resin-forming composition contains a polyether-ene such as a polyallyl glycidyl ether, a free radical-polymerizable monomer such as an acrylate ester, a free radical initiator such as an organic peroxide and/or an organic hydroperoxide and a promoter such as an amine and/or polyvalent metal carboxylate.
