Abstract
Styryloxy compounds of the formula IV ##STR1## wherein R.sup.1 and R.sup.2 are H, or one of R.sup.1 and R.sup.2 is H and the other is methyl; R.sup.7 and R.sup.8 (which may be the same or different) are H, C.sub.1 -C.sub.5 alkyl or C.sub.1 -C.sub.5 alkenyl; or one of R.sup.7 and R.sup.8 may be --OR.sup.6 or C.sub.1 -C.sub.5 alkoxy or C.sub.1 -C.sub.5 alkenyloxy if R.sup.2 is not methyl; R.sup.6 is selected from the group consisting of: ##STR2## where R.sup.10 is C.sub.1 -C.sub.5 alkyl; and R.sup.11, R.sup.12 and R.sup.13, which may be the same or different, are H or C.sub.1 -C.sub.5 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.
