This invention provides method of producing a polymer
which comprises substitution of carboxylic acid group for a terminal halogen group of a polymer obtainable by atom transfer radical polymerization.
The carboxylic acid group may be a carboxylic acid salt group, more preferably a carboxylic acid potassium salt group.
In carrying out the atom transfer radical polymerization in the-practice of the invention, a transition metal complex can be used as a polymerization catalyst. The transition metal complex may be a transition metal complex with an element of the group 7, 8, 9, 10 or 11 of the periodic table as the central atom, more preferably a copper, nickel, ruthenium or iron complex and, in particular, a copper complex is used.
The polymer obtainable by atom transfer radical polymerization is obtained by polymerization of a (meth) acrylic monomer, particularly the polymer obtained by polymerization of an acrylic acid ester monomer.
本发明提供了生产聚合物的方法。
该方法包括用羧酸基团取代可通过原子转移自由基聚合获得的聚合物的末端卤素基团。
羧酸基团可以是羧酸盐基团,更优选的是羧酸钾盐基团。
在本发明实践中进行原子转移自由基聚合时,可使用过渡金属络合物作为聚合催化剂。过渡金属络合物可以是以元素周期表中第 7、8、9、10 或 11 族元素为中心原子的过渡金属络合物,更优选铜、镍、钌或铁络合物,特别是铜络合物。
可通过原子转移自由基聚合获得的聚合物是通过(甲基)丙烯酸单体聚合获得的,特 别是通过丙烯酸酯单体聚合获得的聚合物。
