Example Embodiment

[0104] Example

[0105] Hereinafter, examples and comparative examples are shown to specifically describe the present embodiment, but the present invention is not limited to these examples. In addition, the following "%" is a mass basis unless otherwise specified. In addition, the weight average molecular weight is calculated using gel carrier liquid chromatography (HLC-8120 GPC TOSOH CORPORATION) in terms of polystyrene. .

Example Embodiment

[0107] Synthesis example 1

[0108] In a reaction vessel equipped with a stirring device, a thermometer, and a condenser, 288 g (0.36 mol) of polycarbonate diol derived from 1,5-pentanediol and 1,6-hexanediol was added as a polyol component ( Asahi Kasei Chemicals Corporation, T5650J, number average molecular weight 800), 45g (0.09mol) bisphenol A type propylene oxide adduct diol (ADEKA CORPORATION, BPX33, number average molecular weight 500), 81.4g (0.55mol) ) Dimethylolbutyric acid as dimethylolalkanoic acid, 11.8g (0.16mol) of n-butanol as a molecular weight regulator (reaction terminator), and 250g of carbitol acetate as a solvent (manufactured by Daicel Corporation) , Dissolve all the raw materials at 60°C.

[0109] While stirring the polyol component, 200.9 g (1.08 mol) of trimethylhexamethylene diisocyanate as a polyisocyanate was added dropwise through a dropping funnel. After the dropping was terminated, the reaction was continued while stirring at 80°C, and the absorpt...

[0111] Synthesis Example 2

[0112] In a reaction vessel equipped with a stirring device, a thermometer, and a condenser, 360g (0.45mol) of polycarbonate diol derived from 1,5-pentanediol and 1,6-hexanediol was added as a polyol component ( Asahi Kasei Chemicals Corporation, T5650J, number average molecular weight 800), 81.4g (0.55mol) of dimethylolbutyric acid as dimethylolalkanoic acid, and 11.8g (0.16mol) as molecular weight regulator (reaction terminator) N-butanol, 250 g of carbitol acetate (manufactured by Daicel Corporation) as a solvent, all the raw materials were dissolved at 60°C.

[0113] While stirring the polyol component, 200.9 g (1.08 mol) of trimethylhexamethylene diisocyanate as a polyisocyanate was added dropwise through a dropping funnel. After the dropping was terminated, the reaction was continued while stirring at 80°C, and the absorption spectrum of the isocyanate group (2280cm -1 ) Disappears and the reaction ends. Carbitol acetate was added so that the s...
