Title:
ETHYLENE COPOLYMER WITH IMPROVED ELASTICITY AND PROCESSIBILITY
Document Type and Number:
WIPO Patent Application WO/2012/008794
Kind Code:
A3
Abstract:
Provided is an ethylene copolymer with improved elasticity and processibility. More specifically, provided is an ethylene copolymer which exhibits a high zero shear viscosity and a large degree of shear thinning degree, and shows rheological characteristics behaviors differentiated from products manufactured by using the existing metallocene and Ziegler-Natta catalysts. In addition, provided is an ethylene copolymer which has a low processing load, shows differentiated behavior in Van-Gurp Palmen analysis, and exhibits excellent Neck-in characteristics.
