摘要： Methods for processing LLDPE recyclates including, but not limited to, polyethylene and polypropylene and compositions therefrom are provided. LLDPE recyclate can be visbroken to improve processing characteristics and/or devolatilized to remove waste byproducts to produce processed LLDPE recyclates. Processed LLDPE 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 LLDPE recyclate and/or pre-consumer polyolefins.

摘要： A multilayer film having enhanced toughness and optical properties is provided. The multilayer film includes a base layer, an outer layer, and a tie layer between the base layer and the outer layer. The multilayer film can also include additional layers. Methods for making such multilayer films are also provided. Multilayer films according to the present invention are particularly useful packaging applications where rupture resistance and high clarity are desirable.

摘要： The present disclosure provides a peroxide-modified polyethylene, related compositions, and wire-and-cable products made therefrom. The process for preparing the peroxide-modified polyethylene including the steps of: (A) preparing a first Ziegler-Natta-catalyzed polyethylene in a first reactor; (B) transferring the first Ziegler-Natta-catalyzed polyethylene from the first reactor to a second reactor; (C) admixing a first amount of an organic peroxide to the second reactor; (D) reacting the organic peroxide with a polyethylene composition made from or containing the first Ziegler-Natta-catalyzed polyethylene, thereby coupling the polyethylene components and forming the peroxide-modified polyethylene; and (E) collecting the peroxide-modified polyethylene.
