Nicotine polymer gel

The emulsion copolymerization of 66.7 parts N-30 vinylpyrrolidone and 28.6 parts lauryl methacrylate is carried out in 200 parts water containing 5 parts sodium stearate and 1.25 parts 30% hydrogen peroxide as catalyst. 

The mixture is heated with stirring and the polymerization is carried out at 75°C for about 10 hours. The conversion is approximately 92%. 

The emulsion is spray dried at about 210°C to yield a fine, off-white powder. 

The nitrogen content of the copolymer is 8.6%, indicating an item 1 content of 68%. 

Charge items 3, 4, 5 (90%), and 6 in a melting vessel after passing it through a stainless steel sieve, and heat to melt.
