Metallocene-Produced Polyethylene For Glossy Plastic Containers

A process for forming a plastic container comprising:

• preparing a catalyst system comprising
• a metallocene catalyst represented by the following formula
• (C5R′k)gR″s(C5R′k)MQ3-g
• wherein (C5R′k) is a cyclopentadienyl or substituted cyclopentadienyl, each R′ is the same or different and is hydrogen or a hydrocarbyl radical such as alkyl, alkenyl, aryl, alkylaryl, or arlalkyl radical containing from 1 to 20 carbon atoms or two carbon atoms are joined together to form a C4-C6 ring, R″ is a C1-C4 alkylene radical, a dialkyl germanium or silicon or siloxane, or an alkyl phosphine or amine radical bridging two (C5R′k) rings, Q is a hydrocarbyl radical such as aryl, alkyl, alkenyl, alkylaryl, or aryl alkyl radical having from 1-20 carbon atoms, hydrocarboxy radical having 1-20 carbon atoms or halogen and can be the same or different from each other, and M is a group 4b, 5b, or 6b transition metal;
• contacting the metallocene catalyst with at least one monomer, wherein the at least one monomer comprises ethylene to form an ethylene polymer;
• blow molding the ethylene polymer to form the container, wherein the container has a container wall formed of at least one layer having an external surface a gloss of at least 40.
