Abstract
Addition polymerizable polyethers having pendant ethylenically unsaturated urethane groups are usefully employed as flooring materials and in other applications utilizing radiation curable or chemically curable materials. Such urethane polyethers are advantageously prepared by reacting a polyether polyol such as a hydroxy terminated polypropylene glycol with an isocyanatoalkyl ester of an ethylenically unsaturated acid such as 2-isocyanatoethyl methacrylate.
