Embodiment 1
[0046] Synthesis of Alkali-Soluble Resin:
[0047] In a 1L three-necked flask, add 10g 22' azo (2.4 dimethylvaleronitrile) and 500g tetrahydrofuran, 25g methacrylic acid, 25g hydroxypropyl methacrylate, 25g styrene and 25g n-butyl methacrylate, after nitrogen replacement , stirred slowly at 62°C for 10 hours, precipitated in diethyl ether, removed the solvent by vacuum filtration, and dried in vacuum below 30°C to obtain the alkali-soluble resin R. The weight-average molecular weight is MW10000 when converted to styrene by GPC detection.
[0048] Manufacture of 1,2 naphthoquinone diazide compound PAC1:
[0049] The structure is 44'-(1(4(1(4-hydroxyphenyl)1-methylethyl)phenyl)ethylene)bisphenol 1.2-diazinaphthoquinone-5-sulfonate, passed through 1 mole Condensation of 44'-(1(4(1(4-hydroxyphenyl)1-methylethyl)phenyl)ethylene)bisphenol with 2 moles of 1.2-diazinaphthoquinone-5-sulfonyl chloride Response gets.
