<p>This invention relates to reactive polymers, e.g., aqueous emulsion polymers, having pendant flexible or dangling side chains prepared from ethylenically unsaturated isocyanates. The reactive polymers contain ethylenic unsaturation near the surface or in the surface area of the particles that form the polymers, the ethylenic unsaturation being connected to the polymer through the pendant flexible or dangling side chains. This invention also relates to the process for preparing the reactive polymers, to cross-linkable formulations based on the reactive polymers, and to thermoplastic and cross-linked films prepared from the reactive polymers. The reactive polymers are useful as decorative and functional coatings, inks, adhesives, textile coatings and sealants.</p> |
