Cupric salts used in redox polymerization of ethylene chlorotrifluoroethylene copolymer |
摘要 |
The present invention is an improved process for the aqueous copolymerization of ethylene and chlorotrifluoroethylene in the presence of a catalyst. The catalyst comprises an oxidizing agent and a reducing agent with a sufficient amount of a water soluble buffer compound to maintain the pH from above 7 to about 10. The improvement comprises the addition of from 0.1 to 10 parts per million preferably 1 to 10 parts per million by weight of a cupric cation based on the weight of the aqueous medium.
