| description | In this article, kinetic feature of N, N-diallylpiperidine bromide radical polymerization is investigated. Orders of reaction are determined by the monomer and by the initiator. Essential value in this regard acquire investigation of implementation mechanism on elementary acts of radical polymerization N-alkyl - N, N-diallylamines and their proton salts at initial extents of transformation in water and water-organic solutions. Specific cyclolinear polymerization of diallyl monomers salt allows excluding the act degraded transfer of the chain on monomer and gives the chance of receiving polymers with high molecular weight. Data of kinetic researches testify the lack of degradation inherent chain transfer. It is noted that polymerization rate decreases while adding monomer ethanol to water solution. NMR 13C-spectroscopic researches of the polymers received by radical polymerization of N, N-diallylpiperidine bromide testifies the existence in chains of macromolecules as to five - (48%), and six-membered cycles (52%) which are calculated from a ratio of intensity of signals of the corresponding carbon atoms. The combination of polymeric, surface active and electrolytic properties of the synthesized polymer leads to the new qualitative state possessing a number of specific features shown in conformational and electrochemical behavior of polymer solution. Finding these properties will cause assessment opportunities of synthesized polymer usage as cationic flocculants, coagulants, precipitators and other purposes. Therefore, as distinct from anion and nonionic flocculants, cationic flocculants show high efficiency on application of them for extraction of organic and colloidal pollution and sedimentation of the weighed particles. Besides big advantage of cationic flocculants is the absence of their corrosion action on metals. |
