Azobisisobutyronitrile → Allyl methacrylate

Participants

Reaction Steps

The dimer of allyl methacrylate, which was prepared according to Example 1, was added to the mixture containing 70 wt.-% N-vinylpyrrolidone and 30 wt.-% tert-butyl methacrylate in the amount of 1 wt.-% on the whole mixture. The mixture was polymerized in a polypropylene mold at 60° C. for 16 h in the presence of 0.4 wt.-% azobisisobutyronitrile. The resulting gel was opalescent and contained, after swelling with water, 47 wt.-% water at G=1.238 MPa. The content of soluble extract was 3%.
