Acrylamide radiation-induced polymerization

III. KINETICS OF RADIATION-INDUCED POLYMERIZATION OF ACRYLAMIDE IN AQUEOUS SOLUTION... [Pg.120]

The reported values for the exponent of the dose-rate for the polymerization rate in gamma radiation-induced copolymerization of acrylamide with methyl chloride salt of A, A -dimethylaminoethyl methacrylate (DMAEM-MC) in aqueous solution was found to be 0.8 [16]. However, the dose-rate exponent of the polymerization rate at a lower dose-rate was found to be slightly higher than 0.5 for gamma radiation-induced polymerization of acrylamide in aqueous solution [45,62]. [Pg.124]

TXN undergoes solid-state polymerization by chemical-induced processes as well as by radiation. That TXN may undergo polymerization in the solid state was observed as early as in 1930 U1), but for a long time this observation was not used. In 1954 Mesrobian et al. published the first paper on the radiation-induced polymerization in the solid state (acrylamide polymerization) 1121 and the solid-state polymerization of TXN was rediscovered a few years later 113). Radiation-induced solid-state polymerization of TXN gained importance and it was believed that it could lead... [Pg.122]

Hoffman and his coworkers have done a lot of work on the apphcation of radiation-induced graft polymerization for medical apphcation. The hydrophilic polymers that have been used for radiation-induced grafting are Al-vinyl pyrohdone (NVP), 2-hydroxyethyl methacrylate (HEMA), acrylamide (AAm), acrylic acid (AAc), glycidyl methacrylate (GMA), ethyleneglycol dimethacrylate (EGDMA), and ethyl methacrylate (EMA) onto sihcone rubber were widely smdied. [Pg.244]

The use of radiation-induced free radical sites in tissues to Initiate the polymerization of acrylamide revealed the presence of centers of damage in the mlcrosomes and heavy mitochondria of rat cells.90,91... [Pg.350]

An extensive study has been made of the graft polymerization of vinyl monomers (e.g. methyl methacrylate, sodium vinyl sulphonate, 4-vinylpyridine, acrylamide, and acrylic acid) onto dissolving pulp and groundwood initiated by acetic acid and hydrogen peroxide. It is possible to predict accurately the extent of grafting and the properties of the graft copolymers. The effects of solvents on the radiation-induced grafting of vinylpyridines onto cellulose have been examined. ... [Pg.463]

The photochemical UV radiation method was first employed by Leong and Candau [41] for the radical polymerization of acrylamide in inverse microemulsions stabilized by Aerosol OT. The polymerization was carried out using AIBN initiator and induced by UV irradiation. It was shown that the use of a microemulsion rather than an emulsion led to stable and clear microlatices d 50 nm) of uniform size, thus providing a way to overcome some of the problems of conventional inverse emulsion polymerization, such as instability of the latexes resulting in rapid flocculation and a broad particle size distribution. [Pg.70]
