摘要： 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.
