摘要： A process for preparing an ethylene terpolymer comprising the steps of: (a) pre-polymerizing ethylene and at least one C4-C12 comonomer to produce a copolymer component (i o ) having a MFR 2 in the range of 30 to 80 g/10min; (b) in the presence of component (i o ), copolymerizing ethylene with a C4- C12 comonomer to produce component (i) wherein the MFR 2 of component (i) is in the range of 30 to 80 g/10min; (c) in the presence of component (i), polymerizing ethylene and at least one C4-C12 comonomer to produce component (ii); wherein the MFR 2 ratio of (i)/(i o ) is in the range of 0.5 to 2.5; wherein the MFR 2 of the terpolymer is 1.5 to 10 g/10min, and wherein the density of the terpolymer is 905 to 940 kg/m 3 . An ethylene terpolymer, such as a multimodal ethylene terpolymer, comprising: (i o ) 0.5-5.0 wt.% of a copolymer of ethylene and at least one C4-C12 comonomer having an MFR 2 of 30 to 80 g/10min; (i a ) 25-69.5 wt.% of a copolymer of ethylene and at least one C4-C12 comonomer different from (i o ) wherein the MFR 2 of components (i o ) and (i a ) combined is 30 to 80 g/10 min and wherein the MFR 2 ratio of (i a + i o )/(i o ) is in the range of 0.5 to 2.5; and (ii) 30-70 wt.% of a copolymer of ethylene and at least one C4-C12 comonomer different from (i o ) and (i); wherein the MFR 2 of the terpolymer is 1.5 to 10 g/10min, and wherein the density of the terpolymer is 905 to 940 kg/m 3 .

摘要： A process for polymerizing ethylene in the presence of a polymerization catalyst by copolymerizing ethylene with a comonomer selected from the group of C4-C10 alpha-olefins in three polymerization stages. The polymers produced in the three stages have different melt flow rates. The polymer composition produced by the process has good mechanical properties and can be used for making pipes. The process has a good productivity and provides a stable and economic operation.
