ABSTRACT:
The evolution of smoke and the development of flame are retarded by the incorporation of hydrated magnesium oxychloride into organic polymers which contain aromatic components, particularly polymers and copolymers of styrene. The hydrated magnesium oxychloride has the added advantage that it has low tinting strength, i.e., does not greatly change the color or appearance of the polymers.
