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.
