Abstract: Special quaternary ammonium salts of 2,4,6-tris-( omega -dialkylamino-alkyleneamino)-triazines and 2,4,6-tris-( omega -dialkylaminoalkoxy)-triazines and their use in dyeing anionic polyacrylonitrile fibers with basic dyes; these special derivatives of triazine are particularly effective retarders.

Abstract: Prepn. of a low-melting foam suppressor in fine particulate form comprises spraying the foam suppressor melt onto fine particles of inert, inorganic support material 0.2-4 pts. wt. of foam suppressor melt and one pt. wt. of carrier material having a mean particle dia. less than 100 micron are used; the carrier particles are at a higher temp. than the m.pt. of the foam suppressor and spraying is carried out until the mixt. agglomerates to particles of dia. 100-1500 micron; there after 0.02-0.3 pts. fine particles having a softening point above the temp. of the mixt. are added and the mixt. is allowed to cool to below the melting temp. of the suppressor. Used as a foam suppressor for household washing powders where the basic anionic constituents tend to excessive foam prodn. Method enables a low-melting foam suppressor to be produced in a powdered form which has a long shelf life. The later addn. of the quantity of powder, which may be the same material as the original carrier material, results in stabilisation of the agglomerated material.

Abstract: Method for prodn. of aq. dispersns. of polyolefin, fibrides by dispersing fibrides of aliphatic olefin polymers, opt. in admixt. with cellulose fibres, in water in the presence of a dispersing agent comprising cpds. of formula (I) or salts (b): (where R' = satd. or olefinically unsatd. C7 to C25 alkyl grp., R2 = OH, NH2, R4 = H, CH3; R5 = CH3, C2H5; n = 0 to 50; m = 0 to 15; x = Cl, Br, I or OSO3CH3). The aqs. dispersions may be used to prod. surface structures similar to paper and textiles. The dispersns. cause almost no foam in paper machines and the bonding between synthetic short fibres and those of cellulose is not disadvantageously influenced.

Abstract: Title cpds. of formula (I): (where R1 is opt. branched 1-6C alkyl opt. substd. by OH gps, or two R1 gps. together with the N atom form a 4-7C heterocycle; R2-R4 are each a cyclic, linear or branched, satd. or contg. an olefinic link 1-30C alkyl, opt. substd. by OH gps. and opt. interrupted by ether bridges, or a phenyl or benzyl gp. opt. substd. by Cl or 1-12C alkyl; R3 and R4 may also represent H or a pair of free electrons; R5 is H or 1-4C alkyl; Z is 2-6C alkylene, opt. substd. esp. by OH gps. or interrupted by either or ester gps; X- is an (in)organice anion; and these various anions may be the same or different; n is a whole no. 1-3), are prepd. by quaternising the corresp. unguaternised cpd. They are effective in amts. of 0.003-1.5 wt. % w.r.t. anionic polyacrylonitrile fibres.
