Abstract
Abstract The preparation and properties of some poly[RN(CH2CH[dbnd]CH2)2hydrochlorides], where R may be methyl, n-propyl, n-hexyl, benzyl, and allyl, are discussed. Water-soluble polydiallyl-amine hydrochlorides have been prepared in high yields both by γ-irradiation and by chemical initiation. The polymers were characterized by solubility measurements, IR spectra, NMR spectra, and molecular weight determinations. Polydiallyl-amines as their free bases were found to gel both in solution and in the solid state; the factors influencing gelation were investigated. The polymerization of a mixture of methacrylamide and either methyl-or n-propyldiallylamine hydrochloride by chemical initiation and γ-irradiation in water, dioxane, and dimethylformamide was studied, and evidence is presented for and against the formation of a true copolymer. In all polymerizations, substantial quantities of either amine monomer or amine homopolymer were isolated. Although the amount of amine incorporated into the “copolymer” incr...
