Metallocene-produced very low density polyethylenes

Abstract

Exposed by using metallocene catalysts for the production of very low density polyethylene (mVLDPE) and linear low density polyethylene (LLDPE) blends. The density of polymer blends including those with less than 0.916g/cm3 VLDPE catalyzed by metallocene polymers and the VLDPE optimization of polymer is linear and has no long-chain branched, and density of LLDPE polymer with 0.916-0.940g/cm3. The polymer blends is particularly suited for blown and cast film applications.
