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.

Reaction of monohydroxy-fatty acids of the formula

Oxyalkylated fatty acids and their use as solubilizers

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.

1,3-Bis-aryl-glycerol-ethers

1,3-Bis-aryl-2-oxyalkylated-glycerol ethers

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

Manufacture of water-in-oil emulsions

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.
