A method of using a (chainshuttlingagent) reversible chain transfer agent and the pseudo-block copolymers

摘要

A method for forming a copolymer comprising segments or regions of the characteristic or the polymer composition is differentiated by polymerizing an addition polymerizable monomer of 1 or more, and adding a mixture of the monomer or addition-polymerizable monomer Under polymerization conditions, wherein the step of contacting with a composition comprising an olefin polymerization catalyst one, the reversible chain transfer agent and co-catalyst, the growing polymer chain, in which some of the process conditions are differentiated at least below, which is characterized in that it is formed blocks or segments of two or more are formed in the polymer produced several as is the distinguishable chemical or physical, at least.
