^aT_c is the crystalline temperature determined in the first cooling curve of DSC measurement. ^b T_m is the melting temperature determined in the second heating curve of DSC measurement. ^c ΔH_m is the integrated melting enthalpy calculated as the area under the curve of the melting process above the baseline in the second heating curve of DSC measurement. ^d ΔT is the interval of melting temperature from T_m,onset to T_m,end in the second heating curve of DSC measurement. ^e T_g is the glass transition temperature determined in the second heating curve of DSC measurement. ^f T _{g, PE} is the glass transition temperature of PE-domains determined from the first (from left to right) maximum tanδ peak in the tanδ-temperature curve of DMA. ^g T_δ,max is the second (from left to right) maximum tanδ peak in the tanδ-temperature curve of DMA measurements ^h T_m is the melting temperature of PE crystal domains calculated as the inflection point from storage modulus (E′)-temperature curves of DMA measurements. ⁱ E is the Young’s modulus determined by tensile tests at ambient temperature. ^j σ_b is the stress at break. ^k ε_b is the elongation at break. ^l not observed.
