Process to produce low density polymer in a loop reactor |
| abstract |
A method for producing a low density copolymer of ethylene and 1-hexene having a density in the range of about 0.915 to about 0.930 grams/cc in a continuous loop reactor under slurry phase reactor conditions in the presence of a liquid diluent comprising (a) using a prepolymerized solid particulate metallocene catalyst system, (b) combining the catalyst system with a liquid diluent, and (c) agitating the mixture of (b) to form a liquid mixture containing catalyst system particles that are substantially uniform in size, (d) passing this liquid mixture into the loop reactor, (e) not adding any hydrogen, (f) employing the temperature in the range of about 170° F. to about 180° F., (g) employing ethylene in an amount equal to about 5 to about 6 weight % of the liquid diluent and the loop reactor, and (h) employing 1-hexene in an amount equal to about 1.5 to about 2.5 weight % of the liquid diluent in the loop reactor. |
