    • In line with this conclusion, we found that, in poly(propene-2-d) samples prepared at 80 °C and low monomer concentration in the presence of the investigated catalyst system, the fraction of monomeric units with the D label migrated to position 1 or 3 as a result of growing chain epimerization is <2 mol %.
