  • Publication number: 20100305362
    Abstract: Aminoalkyl vinyl ethers comprising alkylenimine units and of the formula H2?CH—O—X—NH—[Al—]n—H??(I), in which [Al—]n is a linear or branched oligoalkylenimine chain having n alkylenimine units, n is a number of at least 1 and X is a straight-chain or branched C2- to C6-alkylene group, and salts of the monomers I with mineral acids or organic acids and quaternization products of the monomers I with alkyl halides or dialkyl sulfates, processes for the preparation of the compounds of the formula I by addition reaction of alkylenimines with amino-C2- to C6-alkyl vinyl ethers and use of the aminoalkyl vinyl ethers comprising alkylenimine units and of the formula I as monomers for the preparation of polymers for use in the paper industry, as antimicrobial coating materials, in detergents and for the treatment of metal surfaces.

  • Publication number: 20100280203
    Abstract: Graft polymers whose grafting base is selected from the group consisting of polymers having vinylamine units, polyamines, polyamidoamines and polymers of ethylenically unsaturated acids and which comprise exclusively oligoalkylenimine side chains as side chains, process for the preparation of graft polymers having oligoalkylenimine side chains, at least one oligoalkylenimine which comprises a terminal aziridine group being grafted onto one of said grafting bases, and the use of the graft polymers thus obtainable as process chemicals in the production of paper, as antimicrobial coating materials, as builders in detergents and for the treatment of metal surfaces.
