The invention provides for polymerization catalyst compositions, and for methods for introducing the catalyst compositions into a polymerization reactor. More particularly, the method combines a catalyst component containing slurry and a catalyst component containing solution to form the completed catalyst composition for introduction into the polymerization reactor. The invention is also directed to methods of preparing the catalyst component slurry, the catalyst component solution and the catalyst compositions, to methods of controlling the properties of polymer products utilizing the catalyst compositions, and to polymers produced therefrom.

Polymerization process

Ethylene inter-polymer blends

A polymer of the invention comprising the comonomers ethylene, one or more alpha-olefins having 3 to 20 carbon atoms, and one or more cyclic dienes having up to 30 carbon atoms, said polymer having a density of at least 0.890 gram per cubic centimeter; long chain branching; a plurality of double bonds; an Mw/Mn ratio ratio (PDI) of at least 2.5; a flow activation energy of greater than about 6.5 kcal/mol; and a Relaxation Spectrum Index (RSI), PDI, and Melt Index (MI), such that RSI&middot;MI,>2.7 and RSI&middot;MI,&middot;PDI,is in the range of about 0.8 to about 60, when a and b are about 0.6 and minus 1.2, respectively.

Enhanced crosslinking terpolymer

Ethylene polymers having a) a Polydispersity Index of about 2 to about 4; b) a melt index, MI, and Relaxation Spectrum Index, RSI, such that (RSI)(MI.sup.0.6) is about 2.5 to about 6.5; c) a Crystallizable Chain Length Distribution Index, L.sub.w /L.sub.n, of about 1.0 to about 9; and d) a density, .rho., and a percent haze when fabricated into films such that the percent haze is less than 370.rho.-330, are provided. These ethylene polymers advantageously combine superior clarity and toughness with low extractables and enhanced processing ease.

Ethylene polymers having enhanced processing ease

An ethylene polymer having a Polydispersity Index of at least about 3.0, a melt index, MI, and a Relaxation Spectrum Index, RSI, such that (RSI)(MI.sup..alpha.) is greater than about 26 when .alpha. is about 0.7, and a Crystallizable Chain Length Distribution Index, L.sub.w /L.sub.n, less than about 3 is provided. Such ethylene polymer has processability equivalent or superior to even conventional high pressure polyethylene at similar melt index, yet need not be made under high pressure reaction conditions.
