    • The triad/pentad relationship for an isospecific site control is [mr] = 2[rr]; [mmmr] = [mmrr] =2[mrrm], and E = 2[rr]/[mr] =1 (test for enantiomorphic site control). E = 0.96 for the polyhexene obtained at 50°C This was true for all polymers obtained with mix-1-ZrCl2, rac-1-ZrCl2 and meso-1-ZrCl2. (Resconi, L.; Abis, L.; Franciscono, G. Macromolecules 1992, 25, 6814 and ref. 28).
