6. (6) We point out that the viscosity measurements were made at 25° C while the GPC measurements were taken at 50 °C. Ideally, both types of measurements should be carried out at the same temperature. However, due to low boiling point of 2MA (∼67 °C), it was difficult to obtain accurate viscosity readings at 50 °C due to evaporation of 2MA during the measurements).
