structure/property relationship

Structure	performance characteristics
first-order and unhindered hydroxyl group	Very fast polymer synthesis, lower temperature or reduced time for crosslinking
Symmetrical structure	Excellent thermal stability, light colored resin
saturated ring structure	Very good hardness and certain flexibility
1,4-Substitution structure	Very high glass transition temperature (Tg), moderate solubility
beta hydrogen	medium weather resistance

Synthesis Tips

- A packed fractionation column is required due to water solubility.
- Melt the contents of the CHDM vessel and stir before taking the sample to ensure a homogeneous mixture of isomers.
- Due to good thermal stability, light-colored resin can be obtained even if the synthesis temperature is 230℃～240℃.
- Two primary hydroxyl groups provide good reactivity and moderate synthesis time.
- Does not require an esterification catalyst, but can also be used.
