[0111] The preparation method of compound (A) described in the application, by weight, comprises the following steps:
[0112] (1) Weigh a certain amount of p-phenylene diisocyanate, containing R 1 Hydroxyl-terminated hydrocarbons of the group, containing R 2 The hydroxyl-terminated hydrocarbon of the group, the catalyst dibutyltin dilaurate and the solvent;
[0113] (2) Add the above-mentioned substances into a three-necked bottle equipped with a reflux condenser, a stirrer, a thermometer and protected by nitrogen, and react at 60-80° C. for 3-20 hours to obtain the product.
[0114] Among them, p-phenylene diisocyanate, containing R 1 Hydroxyl-terminated hydrocarbons of the group, containing R 2 The molar ratio of hydroxyl-terminated hydrocarbons in the group is 1:(0.5-2):(0.5-2).
[0115] The catalyst dibutyltin dilaurate is 0.3-10 wt% of p-phenylene diisocyanate.
[0116] The solvent is at least one selected from toluene, nitrobenzene, ethyl acetate and dioxane.
