PROCESS FOR THE MANUFACTURE OF HALOGENATED POLYMERS |
摘要 |
<p>IMPROVED PROCESS FOR THE MANUFACTURE OF HALOGENATED POLYMERS (E-24) In a process for the continuous halogenation of polymers by contacting polymer and halogenating agent in a continuous flow device in which means are provided for disengaging reaction by-products and unreacted halogenating agent from the reaction mixture, by deforming and disrupting the halogenated polymer surface and injecting an inert and/or reactive gas into the halogenated polymers immediately after reaction thereby neutralizing the product. In a preferred embodiment the process is carried out in an extruder-reactor and an optional, supplementary inert and/or reactive gas scrubbing zone is included. The process is amenable to saturated and unsaturated polymers.</p> |
