Abstract: Normally solid organic solvent-soluble thermoplastic, polyethylenically-unsaturated polyurethane polymers having pendent cardo (cyclic) groups are disclosed. These polymers can be coated to provide coatings that can be worked (sanded) and that under the influence of activating energy, polymerize to coatings which can have excellent solvent and abrasion resistance.

Abstract: Aqueous solvent dispersible, radiation crosslinkable compounds and oligomers containing poly(ethylenically unsaturated) group-containing components and carboxyl groups are disclosed. Each compound is a monoester of a cyclic dicarboxylic acid anhydride and a 2-hydroxyalkylpolyester, said 2-hydroxyalkylpolyester being the ester of a polyepoxide with a monoester which is the monoester of a poly(ethylenically-unsaturated)alkanol and a dicarboxylic acid. These compounds and oligomers are useful in the field of graphic arts and protective coatings.

Abstract: Normally solid, organic solvent-soluble, thermoplastic, polyethylenically-unsaturated, cellulosic polyurethane polymers are provided. These cellulosic polyurethane polymers comprise one or more cellulose ether or ester segments, one or more alkylene moieties having at least two carbon atoms and which can be substituted or interrupted by ether oxygen atoms, ester groups, or phenylene groups, two or more residues of diisocyanates, the segments, moieties, and residues being linked together by linking groups with the proviso that said alkylene moieties contain sufficient ethylenic unsaturation that said polymer can be crosslinked to a solvent-insoluble state.

Abstract: Coated abrasive product and a process for producing same. The coated abrasive product comprises a backing, a make coat, and a size coat, and may contain an optional saturant coat, an optional presize coat, an optional backsize coat, or any combination of said optional coats, in which at least one coat is formed from a composition curable by electromagnetic radiation comprising:(A) a curable portion containing both ethylenically unsaturated groups and 1,2-epoxide groups, which groups can be in the same compound or in different compounds, and(B) a photoinitiator portion.The photoinitiator portion activates both free-radical and cationic curing mechanisms.
