Abstract
Calcium/zinc mixed soaps are provided corresponding to the formula:
(CaO)n .cndot. Zn(OOCR1)2 in which R1 represents one or more alkyl, alkenyl, hydroxyalkyl, hydroxyalkenyl radicals containing 7 to 21 carbon atoms or ketoalkyl radicals containing 11 to 21 carbon atoms and n is a number of 0.1 to 2.5, the basic calcium/zinc mixed soaps being dissolved or suspended in typical lubricants for halogen-containing plastics, prepared by adding calcium oxide or calcium hydroxide to a melt containing zinc soaps Zn(OOCR1)2, where R1 is as already defined, and typical lubricants with low melt viscosities for halogen-containing plastics in a quantity of 0.1 to 2.5 moles of calcium oxide or calcium hydroxide per mole of zinc soap. Such soaps are useful as stabiliser compositions for halogen-containing thermoplastics which contain basic calcium/zinc mixed soaps dissolved or suspended in lubricants. Also provided is a process for the production of the basic calcium/zinc mixed soaps.
