POLY(HEXAMETHYLENE CARBONATE) DIOL 61630-98-6

Nature:
-Poly (hexamethylene carbonate) diol is a solid, usually in the form of colorless or light yellow granules.
-It has good processability, solubility, and weather resistance.
-It has a high glass transition temperature (Tg) and high melting point at room temperature.
Usage:
-Poly (hexamethylene carbonate) diol is widely used in the preparation of polyester resins, spherical ester resins, elastomers, and plastics.
-Due to its heat resistance and weather resistance, it is often used in fields such as automotive components, electronic devices, industrial coatings, weather resistant coatings, synthetic fibers, and medical devices.
-In the pharmaceutical field, poly (hexamethylene carbonate) diol can be used to prepare sustained-release drugs, such as oral capsules or injectables with controlled release effects.
Method:
-The preparation of poly (hexamethylene carbonate) diol is generally carried out through a polyester reaction method.
-Firstly, the polymer is obtained by polymerizing hexamethylene glycol with carbonate monomers.
-Next, the obtained polymer is subjected to post-treatment to remove impurities and undergo dehydration treatment.
-Finally, poly (hexamethylene carbonate) diol can be obtained by drying and crushing through melting or dissolution.
