## Abstract The heat capacity of a linear polyethylene with dimethyl branches, at every 21st backbone atom was analyzed by differential scanning calorimetry (DSC) and quasiβisothermal temperatureβmodulated DSC. This novel copolyethylene (PE2M) is relatively difficult to crystallize from the melt. O
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
