    摘要: Poly-N-acylalkyleneimines corresponding to the following formula ##STR1## are used as an oxidatively crosslinking constituent in paints. In formula (I), R--CO represents the acyl radical of a mono- or polyunsaturated, aliphatic C.sub.16-22 carboxylic acid or a mixture of such radicals, R'--CO represents the acyl radical of a C.sub.1-22 carboxylic acid or a mixture of such radicals and x and y represent the percentages by weight of the particular polymer units, x assuming values of 20 to 100% and preferably 20 to 95% and y assuming values of 80 to 0% and preferably 80 to 5%. The indices m and n independently of one another may assume the value 2 or 3.

    摘要: 2-benzyl-1-alkanol polyglycol ethers having the formula: ##STR1## in which R.sup.1 is a C.sub.6 to C.sub.22 alkyl group; R.sup.2 is a C.sub.2 -C.sub.6 alkylene group; and n is an integer from 1 to about 100.The products are produced by heating a mixture of a ratio of an alcohol having the formula:R.sup.1 --CH.sub.2 --CH.sub.2 OHwherein the symbol R.sup.1 has the same meaning as above with a ratio of from about 1 mole to about 10 moles, preferably 1 to 3 moles, of benzyl alcohol to a temperature of from about 180.degree. C. to 250.degree. C. in the presence of an alkali metal compound, and optionally a hydrogenation catalyst; separating the excess benzyl alcohol from the mixture and alkoxylating the alcohol thus obtained.The polyglycol ether are used as wetting agents, dispersants, emulsifiers and detergents.
