structural/property relationship

structural features

performance characteristics

first-order and unhindered hydroxyl group

polymer synthesis is very fast, and the temperature is lower or the time is reduced during cross-linking

symmetric structure

excellent thermal stability, light-colored resin

saturated cyclic structure

very good hardness and certain flexibility

1, 4-replacement structure span>

very high glass transition temperature (tg ), medium solubility

βhydrogen

medium weather resistance


synthesis prompt
- due to water solubility a packed condenser column is required.
- melt the contents of the chdm container and stir it before taking the sample to ensure a homogeneous mixture of isomers.
- due to good thermal stability, light-colored resin can be obtained even at a synthesis temperature of 230°c to 240°c.
- two primary hydroxyl groups provide good reactivity and moderate synthesis time.
- esterification catalyst is not required but can be used.
