Polyurea-polyurethane acrylate dispersions. |
摘要 |
<p>A polymerizable ethylenically unsaturated urea urethane polymer dispersed in a polymerizable ethylenically unsaturated compound is prepared by a process which comprises reacting a polyisocyanate, at least a portion of which is a diisocyanate, with a polyfunctional amine containing primary and/or secondary amino groups in the presence of: (a) a polyol, at least a portion of which is a polymeric polyol containing ethylenic unsaturation and having a carbon to oxygen ratio of at least 4/1; (b) a diluent which is an ethylenically unsaturated compound free of active hydrogens; and (c) an active hydrogen containing polymerizable ethylenically unsaturated compound; under conditions sufficient to form a polymerizable ethylenically unsaturated urea urethane polymer dispersed in a polymerizable ethylenically unsaturated compound. The aforedescribed urea urethane polymer dispersions are particularly useful in formulating curable compositions suitable for use as adhesives and sealants.</p> |
