A PROCESS FOR SYNTHESIS OF ETHYLENE POLYMERS |
摘要 |
The present invention relates to a non-cryogenic process for the large scale synthesis of disentangled ultra high molecular weight polyethylene (DUHMWPE) polymers. The process comprises of the following steps: a. mixing FI catalyst of formula I with a hydrocarbon solvent containing poly-methyl aluminoxane (P-MAO) co-catalyst in a vessel under stirring before polymerization or directly in the polymerization vessel at a temperature ranging between 25° C. and 29° C. under a dry Nitrogen atmosphere; and lower concentration of co-catalyst resulting in the associated benefits as described earlier in the claims and descriptions. b. pressurizing ethylene in the polymerization vessel and polymerizing ethylene in a solution or a suspension, continuously or batch wise, in one or more stages at a temperature is in the range of 30° C. to 50° C. |
