Abstract
The present invention relates to non-halogenated and non-metal polymerizable flame retardants, their preparation, compositions containing the same and uses thereof. These flame retardants may be polymerized with other ethylenically unsaturated compounds and chemically bound to the resin matrix thus limiting their migration out of the finished product. The flame retardants of the invention are also more environmentally friendly than conventional halogen-based or metal-based flame retardants.
