摘要: Abstract Polymerization of methacrylic acid (MAA) in aqueous system the presence templates (poly N -vinyl-2-pyrolidone, polyethylene glycol, glycol with azo groups) was investigated UO 2 SO 4 as photoinitiator. The overall rate constants were found. post-effect polymerization after switching off lamp examined and ratio k t p Using rotating sector method, life-time macroradicals for without template determined calculated. MAA photoinitiator influences various on photopolymerization are discussed.
