| titleOfInvention | Fully biodegradable aliphatic copolyester containing cyclic sugar alcohol structure and preparation method thereof |
| abstract | The fully biodegradable aliphatic copolyester containing cyclic sugar alcohol structure disclosed by the present invention is formed by copolymerization by introducing a structural unit represented by III on the basis of polyester structural units represented by I and II, wherein Number of structural units: the number of structural units of [Ⅱ+Ⅲ]=1, the number of structural units of III is 1-40% of the number of structural units of I, and the number average molecular weight of the copolyester is 16000-83000g/mol, glass The transformation temperature is -57-4 DEG C, the tensile strength of the obtained film is 8-49 MPa, and the elongation at break is 280-950%. The invention also discloses its preparation method. Because what the present invention introduces is the cyclic sugar alcohol comonomer with good rigidity, nontoxicity, thermal stability and hydrophilicity, and its added amount is relatively low, and the influence of the polymerization reaction rate is limited, thereby not only can make the obtained copolymerization The molecular weight of the ester is high enough, which also endows it with more excellent thermal performance, degradation performance and hydrophilicity, and a greatly improved elongation at break, and the method is simple to operate, mature in process, easy to control and suitable for large-scale industrial production . |
