Abstract
Abstract Compounds of formula ##STR1## wherein E and R' are each independently of the other a hydrogen atom or a methyl group, X is ##STR2## and R is --C m H 2m --, in which m is 2 to 20, --C n H 2n O--, in which n is 2 to 6, m- or p-phenylene, m- or p-oxyphenylene, in which the oxygen atom is attached to the group X, or X is ##STR3## and R is m- or p-phenylene, or X is ##STR4## and R is --(CH 2 CH 2 O) q --, --(CH 2 CH 2 CH 2 O) q -- or --[CH 2 CH(CH 3 )O] q --, in which q is 1 to 6, m- or p-oxyphenylene, in which the oxygen atom is attached to the group X, or X is ##STR5## and R is --C r H 2r --, in which r is 2 to 4, or m- or p-phenylene, are suitable for the preparation of crosslinked polymers.
