The reaction pressure may be normal pressure. Plumbum preparatium can be used in an amount of 4-10 wt%, preferably 5-8 wt%, based on the total weight of the vegetable oil, glycerin and 1, 4-butanediol. The vegetable oil can be one or more selected from soybean oil, rapeseed oil, castor oil, palm kernel oil, etc.
The reactive diluent may be selected from low molecular weight polyols from BASF, such as Sovermol series with viscosities of 300 to 3500mPas at 20 ℃ or 25 ℃, e.g. Sovermol 1102, Sovermol 1092, etc.
The water scavenger may be selected from the oxazolidine series available from ANGS such as ZOLDINE MS-PLUS (3-ethyl-2-methyl-2- (3-methylbutyl) -1, 3-oxazolidine) and the like.
