Abstract
Polymerizable compositions comprise PA0 (a) a compound containing both PA1 (i) at least one acryloyloxy or methacryloyloxy group, PA1 (ii) at least one allyl, methallyl, or 1-propenyl group attached directly to a carbon atom which forms part of an aromatic nucleus or to an oxygen atom or an oxycarbonyl group which are in turn directly attached to such a carbon atom, PA0 the total of the said groups (i) and (ii) being at least three, and PA0 (b) a compound containing at least two mercaptan groups directly attached to aliphatic carbon atoms, in a proportion as to supply at least 0.8 such mercaptan group per allyl, methallyl or 1-propenyl group in (a) but less than 1.0 such mercaptan group in (a) per acryloyl, methacryloyl, allyl, methallyl, or 1-propenyl group. Examples of (a) are 2,2-bis(3-allyl-4-(methacryloyloxy)phenyl)propane, bis(3-methallyl-4-(methacryloyloxy)phenyl)methane, 2,2-bis(3-allyl-4-(3-(methacryloyloxy)-2-hydroxypropoxy)phenyl)propane, 2,6-dimethallylphenyl acrylate, 1-(allyloxycarbonyl)-2,4- and 2,5-bis(3-(methacryloyloxy)-2-hydroxypropoxycarbonyl)benzene, and benzophenone-3,4,3',4'-tetracarboxylic acid X,X'-diallyl esters Y,Y'-bis(3-(methacryloyloxy)-2-hydroxypropyl…
