Abstract
The behavior of kinetic and thermodynamic characteristics of linear low-density polyethylene (LLDPE) crystallinity containing cyclo-olefin copolymer (COC) were investigated by means of differential scanning calorimeter (DSC). The crystallinity kinetic parameters including the crystallinity apparent activation energy (E), rate of crystallinity constant (K) and the order of crystallinity (n) were calculated with Borchardt and Daniels methods. The results have shown that the activation energy of blends increased with increase in the COC loading and the order of crystallinity was the first order for all blends. Gibbs free energy, enthalpy and entropy of the LLDPE crystallinity increased with the loading of COC. The different crystallinity kinetic models of LLDPE were observed with the loading of COC. It was concluded that the COC hindered the chains of polymer from aligning in a row.
