Abstract: Particulate styrene polymers which contain a blowing agent and are surface-coated with from 0.05 to 1% by weight of an ester. The coating agent is a hydroxycarboxylic acid ester, or an ester of a carboxylic acid with an oxyalkylated alcohol; tristearyl citrate is a preferred ester.The styrene polymers can be used to produce foam moldings, with short mold dwell times and good welding of the foam particles.

Abstract: Reaction of monohydroxy-fatty acids of the formulaCH.sub.3 --(CH.sub.2).sub.m --CHOH--(CH.sub.2).sub.n --COOHwhere m is an integer from 4 to 9 and n is an integer from 6 to 11, with from 12 to 20 moles of ethylene oxide, the products thus obtained, and their use as solubilizers.

Abstract: Oxyalkylated 1,3-bis-aryl-glycerol ethers of the formula ##STR1## where R and R.sup.1 are aromatic substituents, R.sup.2 is --CH.sub.3 or --C.sub.2 H.sub.5, R.sup.3 is --H or --CH.sub.3, n is from 0 to 10 and m is from 8 to 50.The compounds of the formula I are used as emulsifiers, preferably in the preparation of print pastes.

Abstract: A method is provided for forming an anti-corrosive oxide layer on steel. The steel surface is subjected to superheated steam for a period of one to several hours. Before subjecting the steel to the superheated steam, the steel surface is initially subjected to a gaseous formic acid atmosphere at a raised temperature of up to 480.degree. C. The treatment with superheated steam takes place during a further heating period in which a temperature between 450.degree. C. and 520.degree. C. is maintained under steam flow-through conditions in which the steam flow has a Reynolds number greater than 900.

Abstract: Water-in-oil emulsifiers are obtained by reacting fatty alcohols with epichlorohydrin and reacting the resulting glycidyl ethers with amine.

Abstract: A method is provided for forming an anti-corrosive, oxide layer on steel. The steel surface is subjected to superheated steam for a period of one to several hours. Before subjecting the steel to the superheated steam, a clean steel surface is initially heated to at least 200.degree. C. in a nitrogen, air, or oxygen atmosphere. The treatment with superheated steam takes place during a further heating period in which a temperature between 450.degree. C. and 520.degree. C. is reached and maintained under steam flow through conditions in which the steam flow is turbulent or should have a Reynolds number greater than 900.

Abstract: A process for the manufacture of reaction products of fatty alcohols and epichlorohydrin, which have been reacted with polyhydric alcohols or their monoethers and may or may not have been further modified with alkylene oxides, the reaction products per se and emulsifiers, solubilizing agents and fat-like materials consisting of these products.
