Molecular weight and
molecular weight distribution analyses of samples were conducted by
using a Malvern OMNISEC RESOLVE gel permeation chromatography (GPC)
system (Malvern, UK) equipped with a refractometer, right-angle and
low-angle light scattering detector (RALS/LALS), and viscometer. Samples
of 1 mg/mL concentration were prepared in HPLC-grade chloroform and
filtered through a 0.2 μm PTFE filter to remove trace contaminants.
The GPC columns (Viscotek T Series; T3000, T4000, and T6000) regulated
at 35 °C were used to facilitate separation with HPLC-grade chloroform
as the eluent set at a flow rate of 1 mL/min. The collected data were
processed and analyzed using OMISEC-v11.10 software.
