摘要： Rubber particles, to be used as fillers or extenders for various composite polymer systems, are chlorinated by a gas-solid phase reaction with a chlorine-containing gas. A composite polymer containing the chlorinated rubber fillers or extenders exhibits a higher flexural modulus than if prepared using an unchlorinated rubber filler or extender. Chlorination of the rubber particles is carried out by contacting the finely divided rubber particles with a chlorine-containing gas comprising at least about 5 volume percent chlorine. Advantageously, the chlorine can be diluted with air, nitrogen or other essentially inert gases and may contain minor amounts of fluorine. Improved performance is obtained with nitrogen dilution of the chlorine gas over air dilution. Improved polymer composite systems having higher flexural modulus result from the use of the chlorinated rubber particles as fillers instead of unchlorinated rubber particles.

摘要： The present invention relates to adducts of a partially hydrogenated acrylonitrile-butadiene rubber and a halogen selected from chlorine and bromine. The preferred adducts are characterized by having a surprisingly low gel content of less than ten weight per cent, as measured by weight per cent insoluble in methyl ethyl ketone after sixteen hours at 30°C.

摘要： A halogenated polybutadiene series elastomer is produced by reacting a polybutadiene series elastomer with a particular active halogen group-containing compound in the presence of a particular organic halogenating agent. The resulting halogenated polyburadiene series elastomer can be subjected to heat-resistant crosslinking with a particular polyvalent amine, and is suitable for the preparation of rubber compositions for tires requiring heat resistance.

摘要： A process for the continuous bromination of butyl rubber polymer by contacting the polymer with a brominating agent in a continuous flow device in which means are provided for disengaging reaction by-products and unreacted halogenating agents from the reaction mixture, by deforming and disrupting the brominated polymer surface and injecting a neutralizing agent into the polymer immediately after reaction thereby neutralizing the polymer, comprising contacting a polymer substantially free of acid scavengers, with the brominating agent at elevated temperatures the bromination reaction being carried out in an acid atmosphere, thereby producing a polymer having a substantial fraction of the bromine in the primary allylic position.

摘要： In a process for the continuous halogenation of polymers by contacting polymer and halogenating agent in a continuous flow device in which the polymer and halogenating agent are subjected to deformation during reaction and in which means are provided for disengaging reaction by-products and unreacted halogenating agent from the reaction mixture, a significant process improvement is realized by injecting an inert and/or reactive gas into the halogenated polymers immediately after reaction in order to neutralize 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.

摘要： Continuous halogenation of polymers is achieved in an extruder-reactor employing reactants, conditions and design features directed to maximizing mixing and contact of the polymer with the halogenating agent and neutralizing agent while simultaneously minimizing side reactions and polymer degradation. The polymer passes through three extruder-reactor zones under controlled conditions to achieve halogenation: feed, reaction, neutralization, and optionally a wash and exit zone. Various halogenated polymers are produced, for example, halogenated linear low density polyethylene and halogenated butyl rubber.
