Determination of monomer conversion by headspace analysis. |
摘要 |
<p>Method for determining monomer conversion in the liquid phase by analyzing vapor phase above a polymerization mixture comprising measuring temperature of the vapor phase, analyzing the vapor phase with a gas chromatograph provided with a flame ionization detector to determine relative amount of a certain monomer in the vapor phase, correlating initial amount of the monomer with an intermediate amount of the monomer adjusted by applying a temperature correction, and determining monomer conversion on the basis of an essentially linear relationship of conversion in the liquid phase with relative amount of the monomer in the vapor phase.</p> |
