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.
