Polymer k value
WebThe gelation time tg necessary for a solution of functional (associating) molecules to reach its gel point after a temperature jump, or a sudden concentration change, is theoretically calculated as a function of the concentration and temperature for the molecules carrying the number f of functional groups. Quite generally, tg is given by the product of the relaxation … WebWhat is K value in conductivity? K-value is simply shorthand for thermal conductivity.
