The synthesis of poly(2-acryloyloxyethyl methacrylate) has been performed followed by its polymerization. The kinetics of photochemically initiated template polymerization resulting in a ladder polymer has been examined. Global reaction rate constants within 293ร313 K, global activation energy, acti
The anionic graft polymerization of 4-vinyl pyridine on the potassium alkoxide derivative of starch or dextrin in dimethyl sulphoxide solution was studied. Graft polymerization occurred only at relatively high alkoxide concentration. The yields of pure graft polymer were low due to extensive homopol

The anionic polymerization and oligomerization of 4-vinyl pyridine by methanolic alkali metal methoxides in DMSO was studied. The molecular weights increased with increasing monomer concentration and decreased with increasing methanol concentration. This fact was utilized in the preparation of oligo
