Abstract: Provided are polymer compositions comprising: a polycondensation polymer; and an encapsulated flame retardant agent, wherein the encapsulated flame retardant agent comprises a passivating coating and a catalytic flame retardant core and wherein the passivating coating has a thickness of from about 1 nm to about 100 nm observed using scanning electron microscopy. The catalytic flame retardant core may be coated via a process of atomic layer deposition.

Abstract: A flame retardant composition comprising: a polycarbonate; a branched polycarbonate comprising bisphenol carbonate units, 0.01 to 1.0 mol % of a repeating unit derived from a monomer having a pendant ester group, or a combination thereof, and repeating units derived from a branching agent based on the total moles of the composition; a linear polycarbonate comprising bisphenol carbonate units and 0.01 to 1.0 mol % of a repeating unit derived from a monomer having a pendant ester group based on the total moles of the composition; a flame retardant comprising an alkyl sulfonate, an aromatic sulfonate, an aromatic sulfone sulfonate, an aromatic organophosphorus compound, or a combination thereof, and optionally a cyclic siloxane; optionally, an additive composition; and optionally, a filler.
