Table 2

Summary of the TRLS experimental results.

Blend	Slope; (at 120°C)	Secondary phase separation	Slope; (at 140°C)	Secondary phase separation
PES-14.3	0.71	✓	0.89	✓
PES-14.3-A	0.41	✓	0.50	✓
PES-14.3-Ca	1.00	✓	1.09	✓
PES-11.4	0.51	✓	0.57	✓
PES-11.4-A	0.48	✓	0.30	×
PES-11.4-Ca	0.55	✓	0.39	×

✓: secondary phase separation occurs, ×: does not occur.
