Reaction Conditions

Reaction Steps

A 25 ml reaction vessel was charged with 12 g ethyl acetate, 2.85 g (0.007 mol) TRIS, 0.95 g (0.008 mol) NIPAM, 0.21 g (0.0008 mol) tridecyl methacrylate, and 0.078 g. 2,2′-azobis(2-methylbutanenitrile). After nitrogen flushing for 3 minutes, the vessel was closed and placed in an oil bath. The polymerization was run for 17.5 hours at 76° C. The polymer was precipitated into deionized water, dried at room temperature (20° C.), dissolved in acetone and precipitated into deionized water. The purified polymer was heated at 50° C. to remove bound water. Upon mixing the polymer with HMDS and casting a film, the film had an elongation of 10%. Upon addition of 2 wt % sucrose acetate isobutyrate to the polymer (10 wt %) in HMDS, the cast films had an elongation of greater than 250% without an increase in tack.
