NOVEL METALLOCENE CATALYST PHILLIPS LOOP-SLURRY BASED POLYETHYLENE RESINS FOR EXTRUSION COATING APPLICATIONS

摘要

Significant advances in our abilities to synthesize novel polyethylene resins for extrusion coating applications are discussed. The new resins were largely equivalent to a conventional HP-LDPE resin in impact, tear, adhesion, sealing, extruder motor loads and pressures at comparable melt index values. Some resins closely approached the neck-in and drawdown of the HP-LDPE resin. These results are discussed in terms of the molecular and rheological properties of these novel resins compared to conventional HP-LDPE resins.
