Compounds of the formula I ##STR1## where R is C.sub.8 -C.sub.20 -alkyl and A is a polyalkylene oxide radical composed of from 4 to 30 alkylene oxide units, of which from 100 to 60 mole % are ethylene oxide units and from 0 to 40 mole % are 1,2-propylene oxide units or 1,2-butylene oxide units or a mixture of these.
摘要:
Films obtained from paints based on conventional aqueous polymer dispersions exhibit improved wet adhesion to alkyd resin-coated substrates and improved blocking resistance if the paints contain polyglycidylamines which carry 2 or more glycidyl groups which are bonded to hydrogen-free nitrogens.
摘要:
Oxyalkylated bisphenols are obtained from 2,2-(p,p'-bishydroxydiphenyl)-propane and styrene in the presence of an acid catalyst and are then oxyalkylated, after which they may or may not be sulfated.
摘要:
Polyester fibers and cellulose fibers, and blends of these fibers, are dyed continuously with disperse dyes, or dispersed dyes, by continuous application of an aqueous dye liquor which contains, as the essential dyeing assistant, a polyoxyalkylated amine, a polyoxyalkylated amine-oxide and/or a quaternized polyoxyalkylated amine which in 1% strength aqueous solution has a cloud point of not less than 18.degree. C and which is derived from amines which contain at least 2 nitrogen atoms and at least one group which can be oxyalkylated, followed by drying and fixing.

A process for fatliquoring, filling and hydrophobicizing leathers and furs, comprises using ene adducts of maleic anhydride with unsaturated fatty acids of from 12 to 24 carbon atoms or their C.sub.1 - to C.sub.20 -alkyl or C.sub.2 - to C.sub.20 -alkenylesters, triglycerides, amides, mono- or di(C.sub.2 - to C.sub.4 -alkanol)amides, mono- or dipolyetheramides or polyetheresters, or ene adducts partially or completely derivatized by reaction with amines or alcohols to form amides or esters, respectively.
摘要:
Petroleum emulsion breakers based on alkoxylated polyethyleneimines are obtained by reacting polyethyleneimine with a molecular weight of 2,500-35,000 with 5-40 moles each of propylene oxide and ethylene oxide per ethyleneimine unit in the polyethyleneimine and are used for the demulsification of petroleum emulsions at from 10.degree. C. to 130.degree. C.
