    Abstract: Paper, card, or cardboard with high dry strength is made by adding to paper pulp mixt. (I) obtd. by heating native potato starch with cationic polymer (II), having K value at least 30, contg. as characteristic monomer units of (A) diallydimethylammonium chloride (III) or (B) N-vinylamine or (C) N-vinylimidazoline of formula (IV) where R1 = H, 1-18C alkyl, or (V); R2 = H, 1-18C alkyl, (VI) or (VII) R3, R4 = H or 1-4C alkyl; R5, R6 = H, 1-4C alkyl, or Cl; and X = acid residue in aq. medium at temp. above pasting temp. of the starch and in absence of oxidising agents, polymerisation initiators, or alkali, followed by dewatering and sheet forming.

    Abstract: Unsaturated phenone derivatives of the general formula I I where R1 is C1-C4-alkyl, cyclopropyl, cyclopentyl, cyclohexyl, indanonyl, tetralonyl, phenyl or phenyl in which some or all of the hydrogen atoms have been replaced by a C1-C4-alkyl, C1-C4-alkoxy or C1-C4-thioalkyl group, or together with R2 or R6 forms an ethylene or propylene bridge, R2 to R6 are each hydrogen, C1-C4-alkyl, C1-C4-alkoxy or C1-C4-thioalkyl, and R3, R4 and R5 may each additionally be hydroxyl, R2 or R6 may additionally together with R1 form an ethylene or propylene bridge and one or more, but not more than three, of the radicals R2 to R6 are a group of the general formula II II or III III where K is C1-C10-alkylene which may contain 1 or 2 oxygen or sulfur atoms, Y is straight-chain or branched C1-C10-alkylene or is C1-C10-alkylene which is substituted by carboxyl, a carboxylate anion, an alkyl C1-C4-carboxylate group or hydroxyl, X is -NH- or -(N-Alkyl)- of 1 to 4 carbon atoms and Z is hydrogen or C1-C4-alkyl.
