Notes:
The bulk polymerization and copolymerization of N-(1,1′-dimethyl-3-oxobutyl) acrylamide oxime have been studied. Polymerization of diacetone acrylamide oxime was carried out with different initiating systems. The rate of polymerization of diacetone acrylamide oxime with azoisobutyronitrile as the initiating system was much higher than with peroxides. However, in the case of perester initiating systems (t-butyl perbenzoate and t-butyl per ethyl-2-hexanoate), cobalt salt promoted the polymerization rate markedly. Diacetone acrylamide oxime readily formed copolymers with a variety of comonomers (crosslinking agents and reactive diluents). Gel permeation chromatography has shown a higher reactivity of diacetone acrylamide oxime with trimethylol propane trimethacrylate as crosslinking agent and N-vinyl-pyrrolidone as reactive diluent. Therefore, the dynamic mechanical analyses presented an increase in Tg with trimethylolpropane trimethacrylate and N-vinyl-pyrrolidone as comonomers. The terpolymer formed with diacetone acrylamide oxime, trinethylolpropane trimethacrylate, and N-vinyl-pyrrolidone exhibited interesting mechanical properties and high temperature behavior.
