Abstract
Polymeric compositions containing organosiloxane units and carbonate units modified by the presence of halogenated organic radicals imparting improved flame retardancy, reduced smoke evolution, and non-drip characteristics are described. Such compositions can be heat-treated alone or in the presence of curing agents to form thermoset products.
