Vinyl polymer, with excellent long-term compressive performance and its application in pipeline

摘要

The present invention relates to an ethylene-based polymer having excellent long-term pressure resistance characteristics, and a pipe using the same and, more specifically, to: an ethylene-based polymer satisfying the balance between excellent mechanical properties and excellent moldability better than a conventional ethylene-based polymer; and a pipe using the same. The present invention relates to: an ethylene-based polymer having a wide molecular weight distribution, and having long-chain branches so as to have a thin lamellar thickness, thereby having excellent long-term pressure resistance characteristics due to an increase in tie molecules; and a pipe using the same.
