Abstract

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<4> to 1.1*10<4> 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.

Description

technical field

[0001] The invention relates to a novel caprolactone-tung oil copolyol polymer and a synthesis method thereof, belonging to the field of macromolecule chemical synthesis. Background technique

[0002] Polycaprolactone (PCL, polycaprolactone) is a polymer with excellent performance. It has attracted extensive attention because of its superior biodegradability and memory, and its related research has also developed rapidly. PCL is a semi-crystalline polymer with a melting point of 59-64°C and a glass transition temperature of -60°C. Such a structure makes PCL have good flexibility and processability, and the product with the original shape can be restored to the original shape after being deformed and fixed by means of external stimulus such as heating. On the other hand, the product of PCL degradation is CO 2 and H 2 O, non-toxic to the human body, has excellent drug passage and mechanical properties, and can be used as biomedical materials (such as in vivo...
