    Abstract: Use of copolymers obtainable by free-radical copolymerisation of (a) C8-C40-monoolefins with (b) ethylenically unsaturated C4-C8-dicarboxylic anhydrides in the manner of a mass polymerisation at from 80 to 300 DEG C to form copolymers having molecular weights of from 500 to 20,000 g/mol, subsequent solvolysis of the anhydride groups of the copolymers and at least partial neutralisation in an aqueous medium with bases of the carboxyl groups formed in the course of the solvolysis and which are present in the form of aqueous dispersions or solutions, as agents for waterproofing leathers and pelt furs.

    Abstract: Described are maleic acid imide alpha -olefin copolymers with a mean molecular weight of 1,000 to 50,000, built up of structural units of the formula I, R being a tetramethylpiperidinyl grouping of the formula II in which R is hydrogen, C1 to C6 alkyl, formyl, C2 to C6 alkanoyl, C1 to C12 alkoxy, C5 to C6 cycloalkoxy, cyanomethyl, 2-Hydroxyethyl, benzyl or a group of the formula -CR = CH-CO-OR , R being hydrogen,C1 to C6 alkyl or a group of the formula -CO-OR , and r being C1 to C18 alkyl, C5 to C8 cycloalkyl, C7 to C18 aralkyl, phenyl or tolyl, where R can also denote, in a quantity of up to 8 mole % relative to II, hydrogen, C1 to C22 alkyl or C5 to C8 cycloalkyl, and R is a mixture of C14 to C28 alkyl groups, two of these alkyl groups, which may not differ from each other by more than two C-atoms, constituting at least 30 % of this mixture. The copolymers described are suitable for use as light-protection agents and stabilizers for organic materials, particularlyplastics and paints.

    Abstract: Polymers of ethylenically unsaturated compounds containing at least one covalently bonded N atom in the molecule, polymerised in the presence of monosaccharides, oligosaccharides, polysaccharides or derivatives thereof, obtainable by free-radical-initiated copolymerisation of (A) monomers or monomer mixtures from the group consisting of (a) N-vinylimidazoles which are substituted on the heterocyclic ring by up to three C1- to C12-alkyl radicals and can be present in N-quaternary form or in salt form, (b) five- to eight-membered N-vinyllactams which can be substituted on the ring by up to three C1- to C12-alkyl radicals, (c) dialkylaminoalkyl acrylates or methacrylates which have a total of up to 30 C atoms in the dialkylaminoalkyl radical and can be present in N-quaternary form or in salt form, (d) N-(dialkylaminoalkyl)acrylamide or N-(dialkylaminoalkyl)methacrylamide which has a total of up to 30 C atoms in the dialkylaminoalkyl radical and can be present in N-quaternary form or in salt form, and (e) diallyl-C1- to C12-alkylamines or salts thereof or diallyldi(C1- to C12-alkyl) ammonium compounds, where as further comonomers to (A) additionally (f) monoethylenically unsaturated C3- to C10-carboxylic acids and alkali metal salts, alkaline earth metal salts or ammonium salts thereof, (g) monoethylenically unsaturated C3- to C10-carboxylic acid esters and (h) small amounts of compounds containing at least two ethylenically unsaturated, non-conjugated double bonds in the molecule can be present, in the presence of (B) monosaccharides, oligosaccharides, polysaccharides, thermally or mechanically treated, oxidatively, hydrolytically or enzymatically degraded polysaccharides, oxidised, hydrolytically or enzymatically degraded polysaccharides, chemically modified mono-, oligo- and polysaccharides or mixtures of the aforementioned compounds (B) in the ratio by weight (A):(B) of (95 to 20):(5 to 80).

Date May 26, 1994Abstract of the Disclosure: Insoluble, only slightly swellable polymers containing amino groups, which can be obtained from popcorn polymers containing units of the structure (I) where R and R1 are H or C1-C4-alkyl, by eliminating the group R-CO- from at least 2% of the incorporated units of the structure I, with the formation of units of the structure II (II) a process for the preparation of the amino-containing popcorn polymers by polymerizing N-vinylcarboxamides and, if desired, other monoethylenically unsaturated monomers copolymerizable therewith with from 0.1 to 10% by weight, based on the monomers used in the polymerization, of a compound containing at least two ethylenically unsaturated non-conjugated double bonds as crosslinking agent, with exclusion of oxygen and polymerization initiators, to form popcorn polymers, and elimination of formyl groups from at least 2% of the copolymerized N-vinylcarboxamides, and the use of the resulting insoluble, only slightly swellable polymers containing amino groups as ion exchangers or adsorber resins for metal ions are described.
