Poly butylene adipate-co-terephthalate (PBAT), also known as polybutylene terephthalate, is a semi-aromatic, biodegradable thermoplastic copolymer that can be easily molded and thermoformed. Poly butylene adipate-co-terephthalate is a random copolymer of 1,4-butanediol, adipic acid, and dimethyl terephthalate (DMT) monomers. PBAT has many attractive properties similar to polyethylene. For example, poly butylene adipate-co-terephthalate has a relatively high elongation at break (30-40%).

Povidone

  Povidone Introduction: Povidone is a polymer material widely used in industry, medicine and chemical research. It is a high-molecular polymer composed of multiple monomer molecules with the same structure, that is, pyrrolidone (pyrrolidone) groups. The degree of polymerization is relatively high, generally hundreds to thousands. It has strong solubility and hygroscopicity, and it will decompose at room temperature, so certain precautions are required when preparing and using it. There are many preparation methods of povidone, the most common of which is the cyclization reaction of γ-butyrolactone and ammonia under alkali catalysis. After the reaction, it is treated with acid water to obtain povidone. The povidone prepared by the method has stable quality, high yield and wide application range. Applications: Povidone has many special chemical and physical properties. First, it has excellent solvent power and can dissolve many other polymer materials as well as some inorganic and ...

Tetrahydrofuran (THF)

Tetrahydrofuran is a heterocyclic organic compound with the molecular formula C4H8O. THF belongs to the group of ethers and is a fully hydrogenated product of furan, a colorless, water miscible organic liquid with a low viscosity at room temperature and pressure. The chemical formula of this cyclic ether can be written as (CH2)4O. Due to its long liquid range, THF is a commonly used medium-polar nonprotonic solvent. Its main use is as a precursor for polymers. Although the odor and chemical properties of tetrahydrofuran are very similar to those of ether, its anesthetic effect is very poor.
