A composition comprising monomeric polyol(allyl carbonate) and a viscosity stabilizing amount of a polymerization inhibitor chosen from the group consisting of dihydroxy atomatics, dioxy aromatics, derivatives thereof, and mixtures thereof in the composition.
A method of inhibiting the thermally induced thickening of compositions containing monomeric polyol(allyl carbonate) comprising providing a viscosity stabilizing amount of a polymerization inhibitor chosen from the group consisting of dihydroxy aromatics, dioxy aromatics, derivatives thereof, and mixtures thereof in the composition.
A method of polymerizing a composition of polyol(allyl carbonate) monomer comprising providing a viscosity stabilizing amount of a polymerization inhibitor chosen from the group consisting of dihydroxy aromatics, dioxy aromatics, derivatives thereof, and mixtures thereof in the compositions whereby to inhibit the thermally induced thickening thereof, and thereafter, without removing the polymerization inhibitor, adding a free radical polymerization initiator to the composition and heating the composition whereby to polymerize the composition.
