| titleOfInvention | Manufacturing method of heat resistant epoxy resin with excellent transparency |
| abstract | An object of the present invention is to provide a method for producing a heat-resistant epoxy resin having excellent transparency suitable for a display material field, an optical element, and an optical modulator, which are transparent and require heat resistance.n n n General formula (1)n n n n n n n n (Wherein R represents an alkyl group and m and n represent an integer of 0 to 3). Production of an epoxy resin for reacting bis (hydroxyphenyl) fluorene (BHPF) with epichlorohydrin In the method, as a BHPF, the yellow index (YI value) in a 10 mm optical path of the solution in which (A) 4 g of BHPF was dissolved in 100 mL methyl ethyl ketone was 6 or less, and (B) fluorenone content rate A method for producing a heat resistant epoxy resin, characterized by using an epoxy resin of 100 ppm or less and having a color APHA120 or less. |
