Abstract
In this paper, melt crystallization of poly(ether ether ketone ketone) (PEE
KK) under strong electric field was investigated. In the crystal structure
of PEEKK, the length of c axis was found to he 1.075 nm, increasing by 7% c
ompared to that of PEEKK crystallized without strong electric field. The mo
lecule chains might take a more extended conformation through the opening o
f the bridge bond angles by increasing from 124 degrees to 144 degrees unde
r strong electric field in the crystal structure.
