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.

摘要： This invention relates to a recycled resin composition having a recycled polyolefin. It also relates to films and package comprising the resin composition. It is thus an object of the present invention to provide a recycled resin composition with improved functional property which is like virgin polyolefin. It is yet another object of the present invention to provide an article having increased inclusion levels of the recycled resin composition without compromising on the processability and functional parameters. The present inventors have found that the mechanical, and in particular the tensile properties of recycled polyolefin are remarkably improved in the recycled resin composition of the present invention when a terminal end of a unit of recycled polyolefin is linked to a functional polymer by a terminal bonding such that the recycled resin composition has a weight average molecular weight from 10000 Kg/mol to 50000 Kg/mol.
