| titleOfInvention | Production of vinyl chloride polymer |
| abstract | PURPOSE: To obtain a vinyl chloride polymer which can give a plastisol of excellent gelation property, by performing the polymerization while adding a compound terminated with an ethylenically unsaturated double bond to the reaction system in the production of a vinyl chloride polymer by, for example, an emulsion polymerization process. n CONSTITUTION: In the production of a vinyl chloride polymer by polymerizing vinyl chloride by an emulsion polymerization process or a fine-suspension polymerization process, the purpose vinyl chloride polymer is obtained by performing said polymerization while intermittently or continuously adding a compound terminated with an ethylenically unsaturated double bond to the polymerization system after the desired polymerization temperature is reached. Examples of the ethylenically unsaturated double bond-terminated compounds which can be suitably used include diallyl phthalate, diallyl maleate and divinylbenzene. With respect to the time of addition, it is suitable that the addition is stared after the polymer conversion reaches 5% and it is stopped before the conversion reaches 40%. n COPYRIGHT: (C)1987,JPO&Japio |
