Method of olefin polymerization in a reactor, such as a slurry loop olefin polymerization reactor, is provided. The method includes conducting in-situ, real time spectroscopic analysis of one or more reactor constituents. The reactor constituents analyzed may be present in the reactor in either the liquid phase or the solid phase, or both. In response to the measured in-situ values, one or more reactor constituents may be metered into the reactor.

L'invention concerne un procédé de polymérisation d'oléfines dans un réacteur, notamment un réacteur de polymérisation d'oléfines en boucle en suspension. Ledit procédé consiste à procéder en temps réel à l'analyse spectroscopique in-situ de un ou plusieurs constituants du réacteur. Les constituants du réacteur analysés peuvent se trouver dans le réacteur soit en phase liquide soit en phase solide, voire les deux. Les valeurs mesurées in-situ permettent ensuite de mesurer un ou plusieurs constituants du réacteur dans le réacteur.
