Abstract: Methods for processing LDPE recy elates including, but not limited to, polyethylene and polypropylene and compositions therefrom are provided. LDPE recyclate can be visbroken to improve processing characteristics and/or devolatilized to remove waste byproducts to produce processed LDPE recyclates. Processed LDPE recyclates are compounded with pre-consumer polyolefins to produce blend compositions having acceptable or even improved processing characteristics. Such pre-consumer polyolefins can also be visbroken to further tailor processing characteristics of such polymer blends. A combination of extruders and/or extruder zones can be used at the same or different locations for visbreaking and/or compounding of both LDPE recyclate and/or pre-consumer polyolefins.

Abstract: This invention provides a flame retardant additive composition which comprises at least one glow suppressant and at least one brominated flame retardant. The glow suppressant is about 0.5 wt% or more of the flame retardant additive composition, based on the total weight of the flame retardant additive composition. The brominated flame retardant contains aromatically-bound bromine and is selected from a) a brominated anionic styrenic polymer having a number average molecular weight of about 750 to about 7500, and/or a bromine content of about 60 wt% to about 77 wt%, b) a brominated anionic chain transfer vinyl aromatic polymer which contains about 70 wt% or more bromine, or a mixture of any two or more of these. Also provided are flame retarded polyolefin compositions that contain at least one glow suppressant and a brominated flame retardant.
