Reaction Steps
The powdered KOH is added slowly to the acrylic acid and the saccharose and water in a reaction flask kept in an ice-water bath. The temperature is kept between 40° and 50° C. After neutralization, the pH-value of the resulting solution is adjusted to 7.8. Then 2-hydroxyethyl methacrylate and the acetophenone are added. The mixture is then poured into the polymerization trough and polymerization is effected by UV-radiation at a bath temperature of 50° C. and a reaction temperature of 60° C. The product is readily millable.
