PROCESS FOR THE PRODUCTION OF HALOGENATED OLEFINICALLY UNSATURATED RUBBER |
摘要 |
<p>Olefinically unsaturated rubber e.g. butyl is continuously halogenated in an extruder-reactor having in sequence a feed zone, first flow restrictor reaction zone, second flow restrictor and neutralization zone. Rubber in the feed zone is formed into a cohesive mass and delivered to the reaction zone where halogenating agent is injected at a filled position and the reactants are subjected to a high degree of mixing; the first restrictor hinders backflow of halogenating agent. Halogenated rubber product mixture is conveyed past the second restrictor, serving to hinder backflow of a neutralizing agent which is injected at or adjacent the downstream end of the restrictor to neutralize the mixture in the neutralizing zone.</p> |
