<p>Styryloxy compound of the formula IV <CHEM> wherein R<1> and R<2> are H, or one of R<1> and R<2> is H and the other is methyl; R<7> and R<8> (which may be the same or different) are H, C1-C5 alkyl or C1-C5 alkenyl; or one of R<7> and R<8> may be -OR<6> or C1-C5 alkoxy or C1-C5 alkenyloxy if R<2> is not methyl; R<6> is selected from the group consisting of: <CHEM> <CHEM> where R<1><0> is C1-C5 alkyl; and R<1><1>, R<1><2> and R<1><3>, which may be the same or different, are H or C1-C5 alkyl, are described as new low viscosity liquid styryloxy monomers which can be photocured and which form transparent polymers. They have an advantageous effect in a mixture with 4-allyloxystyrene, and this mixture has a synergistic effect in combination with divinyl ethers of a polyalkylene oxide.</p> |
