As shown in Scheme 1, the potassium diphenolate intermediates were first obtained by different excess feed ratios of DHBP to DFBN, and then they were readily converted to cyano-terminated PAEK-CN oligomer, named as PAEK-CN-I, PAEK-CN-II, and PAEK-CN-III with the addition of NPN into the reaction mixture, respectively.
b) From calculated number-average molecular weight from the molar ratio of DFBN to DHBP.
60] nanocomposites without DHBP prepared by melt mixing did not show much difference when we restrained the thermal degradation of PP matrix by adding 0.
60] nanocomposites containing DHBP with angular frequency.
60] nanocomposites containing DHBP showed a decrease of tan at low frequency region, corresponding to an increase of the terminal relaxation time (29).
The injection of DHBP was housed in a unfilled area, just after the melting zone.
The secondary decomposition of the DHBP molecules are neglected.
The average residence time modeled varies very little with DHBP concentration.
