The invention discloses a caprolactone-tung oil copolymerized polyol polymer and a synthesis method thereof, and belongs to the field of macromolecular synthesis. According to the method, a mass polymerization one-step method is adopted, low molecular weight tung oil polyol prepared from diethanol amine and tung oil by aminolysis reaction and caprolactone are used as polymerizing monomers, and stannous octoate is used as a polymerization catalyst, and the caprolactone-tung oil copolymerized polyol polymer of which the molecular weight is 0.2*10 to 1.1*10 is synthesized by changing the molar ratio of the caprolactone to the tung oil under protection of an inert gas (N2) at the temperature of 150-170 DEG C. The caprolactone-tung oil copolymerized polyol polymer can be used as a novel polyester to be widely applied to preparation of polymers and copolymers.
