Evaluation of the Degree of Cross-Linking of Epoxy-Acrylate Polymers with a Luminescence Probe

Luminophores, 4,4'-diaminodiphenylmethane and Oxazine-17, were introduced into a photopolymerizable formulation based on an epoxy-acrylate oligomer, and their behavior in thin-film polymerization was studied.     

Postpolymerization of oligoether acrylate formed by reaction of diethylene glycol diglycidyl ether with acrylic acid

Postpolymerization of the epoxy-acrylic oligomer derived from an aliphatic epoxy resin was studied.     

Recombination Chemiluminescence in Photoirradiation of Epoxy Acrylate Polymer Compositions and Its Use for Monitoring of the Network Structure Development

Photoinduced recombination chemiluminescence was applied for monitoring of the network structure formation under UV exposure of films prepared by esterification with acrylic acid of oligomers such as UP-612, ED-16, and Oksilin commercial epoxy resins. The chemiluminescence decay was described in terms of the fractal kinetics model. The spectral dimension parameter, apparent luminescence activation energies, and glass transition temperatures of the polymers were calculated.     

Degree of Cross-Linking of Epoxy-Acrylate Polymers Prepared by Photopolymerization

The degree of cross-linking of epoxy-acrylate polymers prepared by photopolymerization of epoxy-acrylate oligomers was evaluated from the swellability in trichloroethylene.     

Synthesis and Properties of Epoxy-Acrylate Polymers Prepared in the Presence of Sulfoxides and Their Complexes

The initiating activity of some sulfoxides and their complexes in photopolymerization of epoxyacrylate oligomer obtained by the reaction of ED-16 epoxy oligomer with acrylic acid was studied, and the degree of cross-linking of the resulting polymers was evaluated by analyzing their swelling kinetics.     

ESR Study of Photopolymerization of Epoxy-Acrylate Oligomers

Photopolymerization and thermal polymerization of epoxy-acrylate oligomers were studied by ESR at room temperature.     

Copolymerization of N,N-diallyl-N,N-dimethylammonium chloride and vinyl acetate

The free-radical copolymerization of N,N-diallyl-N,N-dimethylammonium chloride with vinyl acetate in DMSO, methanol, and a methanol-water (70: 30, mol %) mixture proceeds to yield statistical copolymers. The nature of solvents significantly affects the reactivity ratios of the comonomers. N,N-Diallyl-N,N-dimethylammonium chloride shows a higher reactivity than vinyl acetate. The kinetic features of the processes have been investigated, and the structure and properties of the copolymers have been studied.
