WebPolymer powders are produced by spray-drying polymer dispersions. In contact with water, the dispersible polymer powder grains disintegrate and release the individual dispersion particles again. The dispersed polymer powder has the same properties as the original dispersion. Polymer powders were first produced in WACKER laboratories in 1957. WebJan 12, 2024 · LogD the distribution constant is a better descriptor of the lipophilicity of a molecule. This can be determined in a similar manner to LogP but instead of using water, the aqueous phase is adjusted to a specific pH using a buffer. Log D is thus pH dependent, hence the one must specify the pH at which the log D was measured. methods of optical navigation
