Table 1 Sample characteristics. The molecular weights and therefore also \({R}_{\max }\) are nominal values based on the GPC calibrations given in the text. Only for PCL a correction factor of 0.56 is known, which would reduce \({R}_{\max }\) to a value of 413 nm75. The melting temperatures (peak maxima) and crystallinities were obtained by DSC heating scans. The samples were cooled from the melt and heated at a rate of \(10\ {{{{{{{\rm{K}}}}}}}}\ {\min }^{-1}\).
