Abstract
A chemical composition and method for the production of polyolefins having enhanced flame retardancy and abrasion resistance properties. Additives are covalently bound to substrate polymers by means of a graft polymerization process. Chemical grafting is facilitated by a novel mixture of graft initiating catalyst and substrate monomers.
