Procedure

The procedure of Example 5 was repeated. The charges of the components were as follows: CSHPU (125.0 g, 20% solids in THF), styrene (STY) (44.0 g), and HEMA (5.44 g). The solution was photolyzed for about 40 hours in order to obtain 80-85% conversion. DSC, GPC, OH equivalent weight, and other pertinent results obtained from the evaluation of the CSHPU/STY/HEMA copolymer obtained are given in Table I. The copolymer obtained was combined with CB-601 isocyanate curing agent and coated according to the procedure of Example 5. The percentage cure at room temperature was measured and set forth in Table I.
