Shear, isothermal and non-isothermal elongational data have been collected for a wide range of linear low density polyethylenes with different structures. In particular the samples differ both in molecular weight and in the comonomer. All the data show that the rheological behaviour is strongly affe
## Abstract A recently developed coarseβgrain model is used to investigate nonlinear rheological properties of model coreβshell systems. The influence of several model parameters on the stresses and shear rates is investigated. Continuous planar elongational flow and superposition rheology are stud
## Abstract **Summary:** The rheological behavior of polyethylenes is mainly dominated by the molecular weight, the molecular weight distribution and by the type, the amount and the distribution of the chain branches. In this work a linear metallocene catalyzed polyethylene (mβPE), a branched metal
