Abstract
Polymeric polyamines are prepared by reacting ammonia or an amine having at least one hydrogen atom bonded to a basic nitrogen atom and having an aliphatic or cycloaliphatic substituent containing 1 to 8 carbon atoms, with a polyepoxy polymer of an ethylenically unsaturated monomer containing recurring oxirane units having a molecular weight of at least 800, and having at least one oxirane group attached laterally to the polymer chain per polymer unit molecular weight of 800 to 1500. Amines specified are mono- and di-methylamine, mono-and diethylamine, butylamine, amylamine, allylamine, ethanolamine, diethanolamine, 2-ethylhexylamine, ethylene diamine, hexamethylene diamine, and cyclohexylamine. The polyepoxy polymer is preferably obtained by polymerizing monomers containing oxirane groups such as glycidyl acrylate, glycidyl methacrylate, glycidyl sorbate, glycidyl vinyl phthalate, glycidyl allyl phthalate, glycidyl allyl maleate, glycidyl allyl ether, glycidyl vinyl ether, 1,2-epoxybutene-3, and allyl alpha, betaepoxyisovalerate, which may be polymerized alone or together with one or more copolymerizable monomers such as butyl acrylate, butyl methacrylate, methyl methacrylate, acrylonitrile, butadiene, chloroprene, vinyl acetate, vinyl ethers, styrene, vinyl chloride, and vinylidene chloride. Polymerization may be carried out in bulk or solution in solvents such as benzene, dioxane, or methyl isobutyl ketone, with the aid of catalysts such as alpha, alphaazodiisobutyronitrile or benzoyl peroxide, to yield polymers preferably in form of oily viscous liquids having molecular weights of 1000 to 3000. By an alternative procedure polymers containing unsaturated hydrocarbon lateral groups may be peroxidized with peroxy-acids, such as peracetic acid and perbenzoic acid, to give oxirane structures. The reaction between the polyepoxy polymers and the ammonia or amines may be carried out at low, room, or elevated temperatures in the presence or absence of an inert solvent such as benzene, dioxane, or water. The after-treated polymers are soluble in dilute acids and may be treated with formaldehyde to yield products which are rendered insoluble on heating. The polyamine products may be used in coating, impregnating and adhesive compositions, as dispersing agents for waxes and oils, and as binders for printing inks and paints.
