THE EFFECT OF IRRADIATION ON THE POLYETHERKETONE WITH CARDO GROUP

Received Date: 13 May 1990

The effects of irradiation on the polyetherketone with cardo group (PEK-C) were studied. It was found that PEK-C can be crosslinked by irradiation under vacuum, while degradation reaction occurred in PEK-C at room temperature in the presence of air. Moreover. it was also found that Ts value of the crosslinked PEK-C at high temperature is higher than that at room temperature in the case of the same gel content, whose value is about 8℃ higher than that of unirradiated PEK-C. The gelation dose of PEK-C at 300℃ under vacuum is 1.5×104Gy,which is about hundred times smaller than that at room temperature.
