    摘要: The use is disclosed of at least one acylcyanamides of the formula ##STR1## in which the symbol R represents a straight or branched chain alkyl or alkenyl group having from 5 to 21 carbon atoms, such group being unsubstituted or substituted by a OH, O--CH.sub.2 CH.sub.2 OH, O--R' group or a mixture thereof, in which R' represents an alkyl group containing from 1 to 4 carbon atoms; in which M is a monovalent or divalent metal cation; and in which n represents the valency of the metal cationto stabilize, thermoplastic molding compositions containing a homopolymer or a copolymer of vinylchloride or a mixture thereof. There is also disclosed heat stabilized thermoplastic molding compositions comprising polyvinylchloride, or a polymer of vinylchloride, and at least one acylcyanamide of Formula I.

    摘要: Stable oil-in-water emulsions containing more than 60% by weight of non-aqueous phase may be prepared using water-soluble salts of monoacyl cyanamides, of which the acyl radical contains from 10 to 20 carbon atoms, as emulsifiers. The monoacyl cyanamides of C.sub.12 -C.sub.18 fatty acids are preferably used in the form of their sodium salts. The oil-in-water emulsions preferably contain from 70 to 95% by weight of non-aqueous phase and from 0.1 to 3% by weight of emulsifier.
