| 摘要 |
<p>The present invention relates to a continuous process for polymerizing a vinyl monomer wherein a liquid reaction mixture flows through a tubular reactor (3) equipped with a primary heat exchanger (2) connected to a primary cooling loop (1) where a primary coolant liquid circulates, optionally cooled by contact with a secondary heat exchanger fitted in the said primary loop and placed in a heat exchange zone of a secondary cooling device containing a secondary coolant liquid. The primary coolant liquid employed in the absence of a secondary cooling device or the secondary coolant liquid consists essentially of superheated water under pressure which produces low-pressure steam which preferably is recovered at least partly thermally or energetically. <IMAGE></p> |
