| titleOfInvention | Producing blocks of block copolymer in a separator downstream of a reactor |
| abstract | A method for producing block copolymers can include polymerizing a feedstock comprising a monomer and a comonomer under first polymerization conditions in the presence of a catalyst in a reactor to produce a first effluent comprising a first polyolefin block, an unreacted monomer, and an unreacted comonomer; blending the first effluent with a coordinative chain transfer polymerization agent to produce a mixture; and polymerizing the mixture in a separator under second polymerization conditions to cause the unreacted monomer and the unreacted comonomer to polymerize onto one end of the first polyolefin block as a second polyolefin block, thereby forming a block copolymer, wherein the first polyolefin block has a first comonomer content and the second polyolefin block has a second comonomer content that is different than the first comonomer content. The method can further include polymerizing in presence of a second coordinative chain transfer polymerization agent in a second separator. |
