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].

A different approach, although stdl working with essentially non-fiinctional polymers has been exemplified [114,115], in which, a 100% solid (solvent free) hot melt has been irradiated to produce pressure-sensitive adhesives with substantially improved adhesive properties. Acrylic polymers, vinyl acetate copolymers with small amounts of A,A -dimethylaminoethyl methacrylate, diacetone acrylamide, A-vinyl pyrrohdone (NVP) or A A have been used in this study. Polyfunctional acrylates, such as trimethylolpropane trimethacrylate (TMPTMA) and thermal stabilizers can also be used.

Lignite can be grafted with synthetic comonomers to obtain lignite fluid loss additives [873]. Comonomers can be AMPS, N,N-dimethylacrylamide, acrylamide, vinylpyrrolidone, vinylacetate, acrylonitrile, dimethylaminoethyl methacrylate, styrene sulfonate, vinyl sulfonate, dimethylaminoethyl methacrylate methyl chloride quaternary, and acrylic acid and its salts. 

A terpolymer fonned from ionic monomers AMPS, sodium vinyl sulfonate or vinylbenzene sulfonate itaconic acid, and a nonionic monomer, for example, acrylamide, N,N-dimethylacrylamide, N-vinylpyrrolidone, N-vinyl acetamide, and dimethylaminoethyl methacrylate, is used as a fluid loss agent in oil well cements [1562], The terpolymer should have a molecular weight between 200,000and 1,000,000 Daltons. The terpolymer comprises AMPS, acrylamide, and itaconic acid. Such copolymers also serve in drilling fluids [1892].

The cationic monomer can be a diallyldimethyl ammonium halide, a di-methylaminoethyl acrylate quaternary salt, or a dimethylaminoethyl methacrylate quaternary salt [1635]. The copolymers may be in solid, dispersion, latex, or solution form. 

Copolymers. Copolymers have also been studied (16-18). While one comonomer contains 1-2 quaternary nitrogen in a flexible pendant chain, the other comonomer was nonionic. Copolymers of the methyl chloride salt of dimethylaminoethyl methacrylate (one quaternary nitrogen atom) and dimethylaminoethyl methacrylate (DMAEMA) and of MDTHD (2 quaternary nitrogen atoms) and DMAEMA, N,N-dimethylacryl-amide (NNDMAm) or dimethylaminopropyl methacrylate (DMAPMA) have been studied and the results summarized in Table VI. 

Hydrogels that have the ability to respond to pH changes have been studied extensively over the years. These gels typically contain side ioni-zable side groups such as carboxylic acids or amine groups (Oppermann, 1992 Scranton et al., 1995). The most commonly studied ionic polymers include polyacrlyamide (PAAm), poly(acrylic acid) (PAA), poly(metha-crylic acid) (PMAA), poly (diethylaminoethyl methacrylate) (PDEAEMA), and poly(dimethylaminoethyl methacrylate) (PDMAEMA).

Another system under investigation is the iron/ chromium redox flow battery (Fe/Cr RFB) developed by NASA. The performance requirements of the membrane for Fe/Cr RFB are severe. The membrane must readily permit the passage of chloride ions, but should not allow any mixing of the chromium and iron ions. An anionic permselective membrane CDIL-AA5-LC-397, developed by Ionics, Inc., performed well in this system. ° It was prepared by a free radical polymerization of vinylbenzyl chloride and dimethylaminoethyl methacrylate in a 1 1 molar ratio. One major issue with the anionic membranes was its increase in resistance during the time it was exposed to a ferric chloride solution. The resistance increase termed fouling is related to the ability of the ferric ion to form ferric chloride complexes, which are not electrically repelled by the anionic membrane. An experiment by Arnold and Assink indicated that...
