| titleOfInvention |
Internally coated reaction vessel for use in olefinic polymerization |
| abstract |
A method of preventing or retarding polymer build-up on the internal surfaces of polymerization reactors is provided by this invention. Reduced build-up in vinyl chloride polymerization is obtained by having a phenolic compound coated on the internal surfaces of the reactor vessel and a water phase polymerization inhibitor either combined with the phenolic coating or added to the aqueous polymerization medium. Optionally, a chelating agent is also added with the water phase inhibitor. The process is further enhanced by the presence of water soluble dispersants such as polyvinyl alcohol and methyl cellulose. |
