Title:
重合体の製造方法
Document Type and Number:
Japanese Patent JP7226434
Kind Code:
B2
Abstract:
Provided is a method for manufacturing a polymer whereby a thiocarbonylthio group bound to an end of a polymer can be easily and highly selectively replaced by a hydrogen atom without using a metal. A polymer is produced by a method that comprises: step A for polymerizing a monomer in the presence of a thiocarbonylthio compound to give polymer T having a group [-SC(=S)R1] (wherein R1 represents a monovalent organic group) at one end; and step B for contacting polymer T with a thiol group-containing compound without adding a radical generator to thereby replace the group [-SC(=S)R1] in polymer T by a hydrogen atom.
