IN-LINE POLYOLEFIN BASED ADHESIVE COMPOSITIONS HAVING GRAFT POLYOLEFIN/ELASTOMER COPOLYMERS

摘要

The present disclosure relates to adhesive compositions, processes of forming adhesive compositions, and multi-layer films. The 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: MRXx; 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 C3-C6 cyclic ether: and withdrawing the olefin based polymer from the polymerization zone; and melt blending the olefin based polymer with a graft (polyolefin/elastomer) copolymer to form a polyolefin based adhesive composition, wherein the process is an in-line process.
