    Abstract: Polyalkylamine derivatives of formula ZCH2NH2-nHn (I) are new. (where, n = 0 or 1; z = polyalkyl residue of molecular weight 150-40000; Y = residue of formula (IIa) or (IIb); R, R1 and R2 = H, optionally substituted alk(en)yl, alkinyl, and optionally substituted cycloalkyl, aryl(alkyl) having heteroatom(s); A = alkylene imine residues of formula (III); m = 0-10; Alk = optionally substituted alkylene; R3 = H, alk(en)yl, alkinyl, or aryl or when Y is a residue of formula (IIa) keto residue of formula (IVa); in (IVa): R = as above or when Y = group of formula (IIb), is a cyano residue of formula (IVb) (where, R1 and R2 = as above) or when n = 0 one of the residues Y is optionally a polyoxyalkylene residue (V) (where, q = 1-30; Alk = as above; and E = H or 1-6C alkyl). Preparation of the derivatives is also claimed. Also claimed are lubricant and fuel compositions containing the above derivatives.

    Abstract: The invention concerns aqueous dispersions containing a polyurethane (A), containing structural units derived from compounds of formula (I), in which the substituents have the following meanings: R , R , R each designate hydrogen, C1-C24 alkyl or C6 - C24 alkenyl; R designates hydrogen; R , R a) together designate C4-C10 alkane-diyl, b) each designate C2-C10 alkyl, C5-C8 cycloalkyl or C7-C20 aralkyl, c) each designate a hydroxyl-terminated poly(C2-C4 alkylene oxide), or d) designate an R or R group with the meaning given in (a) to (c) and the other group designating hydrogen or a group of formula (II), in which X designates C2-C6 alkane-diyl; and R has the same meaning as R or R with the exception that R is not a group of formula II, R and R carrying a total of between 2 and 5 hydroxyl groups bonded to aliphatic carbon atoms; and R and/or R optionally carrying 1 or 2 aromatically bonded hydroxyl groups or 1 nitrile, tertiary amino, carboxylic acid or sulphonic acid group which are optionally present in the form of their salts.

    Abstract: The invention relates to aqueous dispersions of reactive gluing agents containing 0.1 to 10 weight per cent of water-soluble or water-dispersible polymeric protective colloids which can be obtained by reacting polymers containing amino groups from the group: polymers containing vinylamine units; polyamidoamines; polyamidoamines grafted with ethylenimine - with diketenes at a weight ratio polymers:diketenes of 10000:1 to 1:3. The invention also relates to a method for producing aqueous dispersions of reactive gluing agents by homogenising said reactive gluing agents in an aqueous solution of at least one of the aforementioned protective colloids at temperatures of 20 to 90 DEG C under the effect of shear forces, and to the use of aqueous dispersions of gluing agents thus obtained as pulp sizing agents in the production of paper, board and cardboard and for hydrophobing cellulose fibers.

    Abstract: The invention concerns aqueous alkyldiketene dispersions containing an alkyldiketene, cationic starch with an amylopectin content of at least 95 % by wt. and the following anionic dispersants: (a) 0.05 to 1.0 % by wt. of lignin sulphonic acid, condensation products of naphtalene sulphonic acid and formaldehyde, sulphonated polystyrene or salts or mixtures of such polymers and (b) 0.05 to 1.5 % by wt. of sulphuric acid half esters of alcohols with at least 10 C-atoms, mono- or diphosphoric acid half esters of alkoxylated alcohols with at least 10 C-atoms, sulphuric acid half esters of alkoxylated alcohols with at least 10 C-atoms, mono- or diphosphoric acid esters of alkoxylated alcohols with at least 10 C-atoms, C12-C30 alkyl sulphonic acids or salts or mixtures of such compounds. The invention also concerns the use of such alkyldiketene dispersions as bulk size in the manufacture of paper, paperboard and cardboard, as well as in making cellulose fibres water-repellent.
