Abstract
On règle la température de polymérisation d'un polymériseur équipé d'un système de refroidissement où la vapeur formée en présence d'un milieu liquide volatil est condensée dans un condenseur à reflux et le gaz non condensable et le condensat sont renvoyés dans le système de réaction pour évacuer la chaleur de polymérisation. On recycle une partie du gaz non condensable dans le système de refroidissement. Le débit du gaz non condensable à recycler et le débit du milieu de refroidissement à introduire dans le condenseur sont réglés en fonction de la température du système réactionnel.
