Abstract
The use of a monomer as the solvent in both components of a urethane polymerization system eliminates the need for the expenditure of much energy to remove solvent from the cured resin. The exotherm of the urethane cure supplies the heat for the activation of a relatively thermally stable free radical catalyst which then catalyzes the curing of the monomer. The two component system is stable in storage.
