POLYETHYLENE COMPOSITIONS HAVING HIGH DIMENSIONAL STABILITY AND EXCELLENT PROCESSABILITY FOR CAPS AND CLOSURES |
摘要 |
A dual reactor solution polymerization process gives high density polyethylene compositions containing a first ethylene copolymer and a second ethylene copolymer and which have high dimensional stability, excellent processability as well as good organoleptic properties and reasonable stress cracking resistance. The polyethylene compositions are suitable for compression molding or injection molding applications and are useful, for example, in the manufacture of caps and closures for bottles, and for example, in bottles containing non-pressurized liquids. |
