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.
Claims12
An addition polymerizable polyether which is represented by the formula:
- Y[(R'"A).sub.m R'"--Z].sub.x
- wherein each A is individually --O--, --S--, ##STR5## wherein R.sub.1 is hydrogen or alkyl;
- Y is hydroxyl, an oxycarbonylamino ester of an .alpha.,.beta.-ethylenically unsaturated carboxylic acid or a residue of an active hydrogen initiator suitably employed in preparation of a polyether;
- each Z is individually hydroxyl, oxyhydrocarbyl, oxycarbonylhydrocarbyl or said oxycarbonylamino ester of an .alpha.,.beta.-ethylenically unsaturated carboxylic acid provided that the polyether contains at least one oxycarboxylamino ester of an .alpha.,.beta.-ethylenically unsaturated carboxylic acid;
- each R'" is individually alkylene or haloalkylene wherein alkylene has at least two carbons;
- m is a whole number such that --R'"A).sub.m --R'"-- has a number average molecular weight from about 100 to about 100,000 and x is a whole number from 1 to 8.
An addition polymerizable composition comprising an addition polymerizable polyether which is represented by the formula:
- Y[(R'"A).sub.m R'"--Z].sub.x
- wherein each A is individually --O--, --S--, ##STR9## wherein R.sub.1 is hydrogen or alkyl;
- Y is hydroxyl, an oxycarbonylamino ester of an .alpha.,.beta.-ethylenically unsaturated carboxylic acid or a residue of an active hydrogen initiator suitably employed in preparation of a polyether;
- each Z is individually hydroxyl, oxyhydrocarbyl, oxycarbonylhydrocarbyl or said oxycarbonylamino ester group provided that the polyether contains at least one of said oxycarboxylamino ester groups, each R'" is individually alkylene or haloalkylene wherein alkylene has at least two carbons;
