Abstract

Silane-functionalized compositions comprising a polymeric brominated flame retardant with a weight average molecular weight (Mw) of equal to or greater than (≥) 1,000 g/mol exhibit improved burn and crush strength properties as compared to silane-functionalized compositions alike in all aspects except that the Mw of the brominated flame retardant is less than (<) 1,000 g/mol.
