Abstract

One of the most important post-reactor modifications of polyethylene is cross-linking. Cross-linking improves some properties of polyethylene such as: environmental stress cracking resistance (ECSR), chemical and abrasion resistance, service temperature etc. In this study the rheological variation due to a peroxide cross-linking reaction of low-density polyethylene (LDPE) was tracked by a combination of creep tests and differential scanning calorimetry (DSC) tests in isothermal conditions. The peroxide was di-cumyl peroxide and its concentration was 2 wt%. The experiments were carried out at 150,160 and 170°C. The aim of the present work is to determine the viscosity in terms of the degree of cross-linking of LDPE in isothermal conditions by a combination of DSC and creep tests.
