Title:
グラフト共重合体およびその製造方法
Document Type and Number:
Japanese Patent JP3549902
Kind Code:
B2
Abstract:
A two stage aqueous emulsion polymerization process for making graft copolymers is described. In the first stage, at least one first ethylenically unsaturated monomer is polymerized in the presence of at least one mercapto-olefin compound to form a macromonomer with terminal functional groups. In the second stage, at least one second ethylenically unsaturated monomer is polymerized in the presence of the macromonomer such that a copolymer is formed with a backbone of polymerized units of the at least one second ethylenically unsaturated monomer and side chains of the macromonomer.
