    • It is an interesting question whether polymerization occurs more rapid than crystallization (a), such that crystallization resembles that of preformed polymers from the melt as in most model studies on crystallization, or whether crystallization occurs more rapid than polymerization (b), such that the polymer chain is directly incorporated into a growing lamella as it is formed at the catalytically active center. While this question currently remains open, it can be noted that the low temperature dependence of lamella thickness found by no means necessarily implies the latter mechanism (b). Rather, the previous studies, which were cartied out at temperatures as low as 80 °C, show that the usual stronger temperature dependence on lamella thickness levels off in the lower temperature regime.
