    Abstract: Process for the production of water-soluble auxiliaries for the papermaking industry by reacting (a) 1 part by weight of a polyamidoamine obtained by condensing 1 mole of a dicarboxylic acid having from 4 to 10 carbon atoms with from 0.8 to 1.4 moles of a polyalkylene polyamine having from 3 to 10 alkyleneamine units and containing up to 8 ethyleneimine units per basic nitrogen atom with (b) 0.1 to 4 parts by weight of an alpha , omega -dichloro polyalkylene oxide obtained by reacting a polyalkylene oxide having from 8 to 100 alkylene oxide units with a compound selected from the group consisting of a thionyl chloride and phosgene and then cleaving the reaction products by heating them to a temperature of from 70 DEG to 150 DEG C. in the presence of a tertiary amine as catalyst, as crosslinking agent, at a temperature above 20 DEG C. in aqueous solution or in a water-soluble organic solvent, the reaction being carried out to a point at which the viscosity of an aqueous solution containing 20% by weight of auxiliary is from 300 to 2,500 mPas.

    Abstract: A curable polyepoxide composition comprises a poly-1,2-epoxide of a linear oligomer of two to four butadiene units or a linear co-oligomer of one to four butadiene units and an alkenylaromatic compound having the general formula in which R1 denotes a hydrogen atom or -CH3, -C2H5, -C3H7 or -C4H9 and R2 denotes a radical R1, -CH=CH2 or Cl, and a curing agent. The polyepoxide may be epoxidized 3 - methylhepta - 1,4,6 - triene; 3 - methylhepta - 1,3,5 - triene; 3 - methyl-hepta - 2,4,6 - triene; octa - 1,3,6 - triene; octa - 1,3,5 - triene; dodecatetraene; methylundecatetraene; dimethyldecatetraene; hexadecapentaene; methylpentadecapentaene; dimethyltetradecapentaene; trimethyltridecapentaene or mixtures thereof or 1-phenyldeca-1,4,8-triene. The curing agents may be polycarboxylic acids their anhydrides in the presence or absence of polyols or amines.ALSO:Linear oligomers of two to four butadiene units or linear co-oligomers of one to four butadiene units and an alkenylaromatic compound, such as 3 - methylhepta - 1,4,6 - triene; 3 - methylhepta - 1,3,5 - triene; 3 - methylhepta - 2,4,6 - triene; octa - 1,3,6 - triene; octa - 1,3,5 - triene; dodecatetraene; methylundecatetraene; dimethyldicatetraene; hexadecapentaene; methylpentadecapentaene; dimethyltetradecapentaene, are epoxidized by peroxy acids or b -hydroxyethylacetyl peroxide. In examples, (1) 3 - methylheptatriene, (2) 1 - phenyldeca - 1,4,8 - triene, (9) mixed isomers of dodecatriene and (10) mixed oligomers containing 4 butadiene units are epoxidized using a methylene dichloride solution of peracetic acid in the presence of anhydrous sodium carbonate to give mixtures of the corresponding epoxides. The mixtures of Examples (1) and (2) are fractionated to give (1) methylheptatriene monoxide and dioxide, and (2) 1-phenyldeca-1,4,8-triene dioxide and trioxide.
