To a 250 ml round bottomed flask equipped with a magnetic stir bar is added 28.0 grams of triphenyltin hydride, 33.0 grams of 91% divinylbenzene, and 0.26 gram of 2,2'-azo-bis-isobutyronitrile. The mixture is placed under a nitrogen blanket and heated to a temperature of from 40° to 45° C. Samples of the reaction mixture are periodically taken and subjected to infrared analysis. The reaction is terminated when the tin-hydrogen absorption at 1850 cm-1 in the infrared spectrum disappears. This occurs after approximately 30 hours of heating the reaction mixture. The product is then stored at 0° C. until used for the preparation of the polymer.
