Synthetic example A-1
[0128] Synthesis example A-1: Production method of alkali-soluble resin (A-1-1)
[0129] A nitrogen inlet, a stirrer, a heater, a condenser tube and a thermometer were arranged on a four-necked conical flask with a volume of 500 milliliters, and nitrogen was introduced and 240 parts by weight of solvent diglyme was added according to the amount shown in Table 1.
[0130] When the solvent in the four-necked conical flask was stirred, the temperature of the oil bath was raised to 85°C, and then the monomer mixture was mixed as shown in Table 1: 30 parts by weight of methacrylic acid monomer (hereinafter referred to as MAA), methacrylic acid ring 30 parts by weight of oxypropyl ester monomer (hereinafter referred to as GMA), 20 parts by weight of butyl methacrylate monomer (hereinafter referred to as TBMA) and 20 parts by weight of styrene monomer (hereinafter referred to as SM), were continuously added to the four-necked conical flask In, and to stir to mix, while raising the ...
Synthetic example B-1
[0133] Synthesis example B-1: Method for producing polysiloxane polymer (B-1)
[0134] On a four-necked conical flask with a capacity of 500 milliliters, a nitrogen inlet, a stirrer, a heater, a condenser tube and a thermometer are arranged, and nitrogen is introduced and 100 grams of solvent propylene glycol monoethyl ether (hereinafter referred to as PGEE) and two are added according to the consumption shown in Table 2. Acetol (hereinafter referred to as DAA) 80 grams.
[0135] When the solvent in the four-necked conical flask was stirred, the temperature of the oil bath was raised to 110°C, and then the silane monomer / polysiloxane: methyltrimethoxysilane monomer (hereinafter referred to as MTMS) was mixed as shown in Table 2 0.40 moles, 0.55 moles of phenyltrimethoxysilane monomer (hereinafter referred to as PTMS) and 0.05 moles of 3-succinic anhydride propyltriethoxysilane monomer (hereinafter referred to as GF-20) were continuously added to the four-neck conical flask In...
Embodiment 1
[0141] Use 100 parts by weight (solid content) of the alkali-soluble resin (A-1-1) obtained in the aforementioned synthesis example A-1-1, and 20 parts by weight of the polysiloxane polymer (B-1) obtained in the synthesis example B-1 (solid content), after adding 500 parts by weight of the solvent propylene glycol methyl ether acetate (hereinafter referred to as PGMEA; D-1), dissolve and mix with a shaker to prepare a curable resin composition. After water was removed from the curable resin composition by the water removal procedure, the properties were measured by the evaluation methods described later, and the results are shown in the table.
