Synthesis and characterization of polymers containing naphthyl‐2H‐benzotriazoles, 2. Polymer synthesis and characterization

摘要

Abstract2‐(2‐Hydroxy‐7‐(meth)acryloyloxynaphthyl)‐2H‐benzotriazoles were polymerized and copolymerized with styrene and methyl methacrylate in dichloromethane using azoisobutyronitrile as the initiator. The polymer composition was determined by UV spectroscopy and compared with elemental analytical data; the molecular weights were determined by GPC. In homopolymerization, low molecular weight products were obtained due to the bulky naphthyl‐2H‐benzotriazole units. In the case of copolymerization with methyl methacrylate it was found, that the composition of the polymers was very close to the initial ratio of the monomers, whereas in copolymers with styrene the amount of incorporated benzotria
