CATIONIC POLY-ELECTROLYTES .4. KINETIC-STUDY OF THE REACTION OF ACRYLIC POLYMERS CONTAINING TERTIARY AMINE GROUPS WITH HALOGENATED COMPOUNDS IN DIPOLAR APROTIC-SOLVENTS

In the reported experiments, the reaction kinetics of halogenated compounds with tertiary amine groups attached at an acrylic macromolecular chain have been studied. Three acrylic polymers were used. Two of them have mainly a structural unit of N,N-dimethylaminopropylacrylamide and the third is poly(N,N-dimethylaminoethylmethacrylate). Dimethylformamide, dimethylacetamide, and dimethylsulfoxide (DMSO) were used as dipolar aprotic solvents. Benzyl chloride and allyl chloride were considered as halogenated compounds with increased reactivity. The reaction kinetics depend on the polymer and halogenated-compound structures as well as the nature of the solvent. In most of the cases the reactions carried out on polymers are accompanied by self-accelerating processes, with the exception of DMSO, which obviously has normal second-order kinetics. The reaction of polymers containing units of N,N-dimethylaminopropylacrylamide are compared with one having a low molecular weight, for instance N,N prime -bis(3-dimethylaminopropyl)glutaramide.
