Title:
HIGH MELT STRENGTH PROPYLENE-BASED POLYMER AND METHOD OF PREPARING THE SAME
Document Type and Number:
WIPO Patent Application WO/2024/090686
Kind Code:
A1
Abstract:
Provided are a high melt strength propylene-based polymer, a method of preparing the same, and a prepolymer composition for preparing the same. Specifically, since the propylene-based polymer according to an exemplary embodiment has a high melt strength measured at about 200°C of 125 cN or more, its processability and productivity are excellent. Another exemplary embodiment provides a method of preparing the propylene-based polymer, and specifically, the propylene-based polymer is prepared by a preparation method including prepolymerizing propylene, ethylene, and diene in the presence of a Ziegler-Natta catalyst, thereby implementing the physical properties of high melt strength.
