a The rule of naming: PEcomplex-temperature-activator and ratio. For example, PENi2-60-M1 means the PE produced by Ni2 under the temperature of 60 °C and the MMAO/Ni ratio of 1000. b M w (kg mol−1), Mw and Mw/Mn determined by GPC. c Determined by DSC. d Data determined from the 13C NMR spectrum using approaches described by Galland et al.63 e Data was gained from monotonic tensile stress–strain tests. f Strain recovery values (SR) were calculated by using the standard formula SR = 100(εa − εr)/εa, where εa is the applied strain and εr is the strain in the cycle at 0 loads after 10 cycles. | |||||||||
