摘要

正

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 1.5×10

which is about hundred times smaller than that at room temperature.
