ABSTRACT:
Compounds useful in making crosslinkable polymers having the formula (I): ##STR1## wherein R is hydrogen or methyl; R.sup.1 is cyano or ##STR2## wherein R.sup.2 is alkyl; Z is --X--R.sup.3 --X-- or ##STR3## wherein each --X-- is --O-- or --NR.sup.4 --, provided at least one --X-- is --NR.sup.4 -- wherein R.sup.4 is hydrogen or alkyl, R.sup.3 is divalent hydrocarbon and D.sub.1 and D.sub.2 together are the carbon atoms necessary to complete a 5 to 7 membered ring. These compounds can be homopolymerized or copolymerized with each other or with other polymerizable ethylenically unsaturated monomers to give crosslinkable polymers. Such polymers can be purified by conventional purification techniques such as dialysis, diafiltration, ultrafiltration without losing their capability of crosslinking. The resulting purified polymers are particularly useful in photographic materials as gelatin extenders, binders or polymeric color couplers.
