^aDetermined by GPC, values ×10⁵ g mol⁻¹.

^bDetermined by DSC;

^cDetermined by using a universal tester.

^dStrain recovery values (SR) were calculated by using the standard formula SR = 100(ε_a − ε_r)/ε_a, where ε_a is the applied strain and ε_r is the strain in the cycle at 0 loads after 10 cycles.

^eBroad and weak endotherms, amorphous-like polyethylenes.
