Rheological characterisation of LDPE materials by means of differential constitutive equations
Original language description
For rheological description of branched LDPE melts (Escorene LD165BW1 a Bralen RB0323) the following differential constitutive equations were used: eXtended Pom-Pom, Phan Thien-Tanner-XPP, and modified Leonov models. There was carried out quantitative and qualitative comparison of efficiency of the predictions determined by these models with the experimental data measured at 200oC. For both materials there were measured linear viscoelastic properties, shear and uniaxial extensional viscosities.

Reologická charakterizace LDPE materiálů pomocí diferenciálních konstitučních rovnic
Czech description
Pro reologický popis rozvětvených LDPE materiálů (Escorene LD165BW1 a Bralen RB0323) byly vybrány následující modely: eXtended Pom-Pom, Phan Thien-Tanner-XPP a modifikovaný Leonovův model. U obou materiálů byly proměřeny lineární viskoelastické vlastnosti, smyková a elongační viskozita.
