## Abstract The heat capacity of a linear polyethylene with dimethyl branches, at every 21st backbone atom was analyzed by differential scanning calorimetry (DSC) and quasi‐isothermal temperature‐modulated DSC. This novel copolyethylene (PE2M) is relatively difficult to crystallize from the melt. O
With the recent development of new catalysts based on specific metallocenes, ethylene polymers with a narrow molecular weight distribution and comonomers placed homogeneously in the polymer chain have been accessible. In particular, bridged amido complexes can be used to integrate defined long-chain
