Tang, Xinde published the artcileControlled grafting of ethyl cellulose with azobenzene-containing polymethacrylates via atom transfer radical polymerization, HPLC of Formula: 135529-02-1, the publication is Journal of Polymer Science, Part A: Polymer Chemistry (2007), 45(9), 1653-1660, database is CAplus.
Graft copolymers of Et cellulose with azobenzene-containing polymethacrylates were synthesized through atom transfer radical polymerization (ATRP). The residual hydroxyl groups on Et cellulose were first esterified with 2-bromoisobutyryl bromide to yield 2-bromoisobutyryloxy groups, which was then used to initiate the polymerization of 6-[4-(4-methoxyphenylazo)phenoxy]hexyl methacrylate (MMAzo) in the presence of CuBr/N,N,N’,N”,N”-pentamethylenetriamine (PMDETA) as catalyst and anisole as solvent. The graft copolymers were characterized by gel permeation chromatog. (GPC) and 1H-NMR. The mol. weights of the graft copolymers increased relatively to the macroinitiator, and the polydispersities were narrow. The thermal and liquid crystalline property of the graft copolymers were studied by differential scanning calorimeter (DSC) and polarizing optical microscope (POM). Photoresponsive property was studied under the irradiation of UV-Vis light in THF solution The graft copolymers have potential applications, including sensors and optical materials.
