From: Catalyst switch strategy enabled a single polymer with five different crystalline phases
a 1H–13C CP-MAS NMR spectra and b 1H–13C INEPT NMR spectra of PE-b-PEO-b-PCL-b-PLLA-b-PGA-1a (pentablock-1a) at different temperatures (RT, 60 °C and 120 °C). The green circles indicate the end group in each block. RT: room temperature.
