Bisphenol A → xanthene bisphenol A

Participants

Reaction Steps

In the same manner as in Synthesis Example 3, except that 1.555 g (manufactured by DAINIPPON INK & CHEMICALS Co., Ltd., “EXA7335”, 3.2 mmol) of 2,7-diglycidyloxy-1,3,4,5,6,8-hexamethyl-9-phenylxanthene, 0.238 g (0.8 mmol) of 4,4′-diglycidyloxybiphenyl and 0.67 g (3.6 mmol) of 4,4′-dihydroxybiphenyl, were replaced by 1.944 g (manufactured by DAINIPPON INK & CHEMICALS Co., Ltd., “EXA7335”, 4.0 mmol) of 2,7-diglycidyloxy-1,3,4,5,6,8-hexamethyl-9-phenylxanthene and 0.821 g (3.6 mmol) of bisphenol A, a xanthene-bisphenol A copolymer type linear epoxy resin was obtained. The amount of the resulting xanthene-bisphenol A copolymer type linear epoxy resin was 2.69 g and the yield was 97%.
