ABSTRACT:
Urea derivatives with .alpha.,.beta.-ethylenically unsaturated carboxyl or carboxamide radicals, produced by reaction of ethylenically unsaturated isocyanates with ammonia or amines or by reaction of ethylenically unsaturated amines with isocyanates in the absence of water, optionally in bulk, it being possible to carry out the reaction for improved reaction control advantageously in inert organic solvents or also in so-called reactive diluents, i.e. copolymerizable ethylenically unsaturated monomeric compounds which remain inert under the reaction conditions, such as for example vinyl esters, (meth)acrylates, vinyl aromatics.
The urea derivatives produced according to the invention have in their monomeric form slight to moderate or in some cases good solubility in water and/or in organic solvents. They are polymerizable or copolymerizable via their .alpha., .beta.-ethylenically unsaturated carboxyl or carboxamide groups and can be multiferiously used by free-radical initiated polymerization or copolymerization for the production of polymers or copolymers.
