MACROMONOMER, ITS SYNTHESIS AND GRAFT COPOLYMER PREPARED BY USING SAME

摘要

PURPOSE:To facilitate the control of the MW of the obtained macromonomer by polymerizing a monomer polymerizable by cationic living polymerization and reacting the formed polymer with a specified terminator to introduce a specified structure into the macromonomer. CONSTITUTION:A monomer (a) which can be polymerized by cationic living polymerization (e.g. 2-methyl-2-oxazoline) is subjected to cationic living polymerization, and the formed polymer is reacted with a terminator (b) which can terminate the polymerization by reaction with the cationic living terminals to obtain a macromonomer of formula I (wherein R1 is H, an alkyl or an aralkyl; A is a homo- or co-polymer of an MW of 50 to 100000 derived from an oxazoline compound, a 1,3-oxazoline compound, a cyclic imide compound, a tetrahydrofuran compound, an unsaturated ether compound, an aromatic vinyl compound, a carbazole compound or a sulfur-containing heterocyclic compound; X is a group of formula II or III or the like; Y is R2Y' or ArY'; R2 is formula IV; (m3) is 0 to 10; Ar is a group of formula V or VI or the like; Y' is -OH, -NH2 or the like; Z is R2Z' or ArZ'; R2 is a group of formula VII, (m4) is M3; and Z' is -H, -OH or the like).
