Process and apparatus for preparation of vinyl polymers |
| abstract |
A process and apparatus for preparing vinyl polymers by continuous bulk or solution polymerization provide improved mixing during polymerization. In the process, fresh polymerization starting material is incorporated into a part of reaction mixture withdrawn from a polymerization zone and then fed to the polymerization zone. Polymerization temperature is kept at 100 DEG to 200 DEG C. and polymer content in a reaction mixture withdrawn from the polymerization zone is kept at 50 to 80% by weight. A tank having agitating means, outlet opening and recycling inlet is used as polymerization reactor. Said recycling inlet is preferably located at a position corresponding to 1/4 or less of the total height from the bottom to the top of the tank. |
