摘要:
Adhesive compositions, processes of forming adhesive compositions, and multi -layer films are discussed herein. Hie processes generally include contacting an olefin monomer with a catalyst system within a polymerization zone to form an olefin based polymer under polymerization conditions sufficient to form the olefin based polymer, the catalyst system including a metal component generally represented by the formula: MR X ; wherein M is a transition metal, R is a halogen, an aikoxy, or a hydrocarboxyl group and x is the valence of the transition metal, wherein the catalyst system further includes an internal donor (ID) comprising a C 3 -C 6 cyclic ether: and withdrawing the olefin based polymer from the polymerization zone; and melt blending the olefin based polymer with a functionalized poly olefin to form a polyolefm based adhesive composition, wherein the process is an in-line process.

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