発明の名称 (英語) LIVING RADICAL POLYMERIZATION INITIATOR, METHOD FOR PRODUCING POLYMER, AND POLYMER
発明の概要(英語) A living radical polymerization initiator represented by general formula (1), which uses a living radical polymerization initiator that comprises, as initiating groups for reactions, two halogen atoms different from each other in reactivity, and which enables different living radical polymerization reactions to proceed with respect to the respective initiating groups. In general formula (1), R1 represents an organic group which is linkable with two or more other organic groups, and which is selected from among an aliphatic group having 1-12 carbon atoms, an aromatic group, a carbonyl group, a sulfonyl group and an organic group obtained by combining two or more of these groups; each of R2, R3, R4 and R5 represents a hydrogen atom or an organic group selected from among an aliphatic group having 1-12 carbon atoms, an aromatic group, a carbonyl group, a carboxyl group and a sulfonyl group; each of X and Y represents a halogen atom; each of m and n represents an integer of 1 or more; and X and Y are different from each other in reactivity with a monomer.
従来技術、競合技術の概要(英語) BACKGROUND ART
Conventionally, a method for obtaining the vinyl polymer is a vinyl monomer, radical polymerization method was well known. In particular, is by switching, an activation of the back bottom in conjunction with the bottom of the foot or the intended, vice versa or a case where the condition occurs, the user can select either the usage of many.
In addition, that a vinyl polymer obtained, having various molecular weights which would cause the mixture of compounds, the vinyl polymer is a narrow molecular weight distribution in a problem that it is difficult to obtain the.
More specifically, to control the reaction, weight average molecular weight (Mw) molecule and a number average molecular weight (Mn) (Mw/Mn) as the ratio, 2-3 only to such an extent that cannot be reduced.
As a method to resolve such a drawback, from circa 1990, the living radical polymerization method has been developed. That is, according to the living radical polymerization method, and the molecular weight can be controlled, and a narrow molecular weight distribution in the polymer can be obtained.
Specifically, Mw/Mn is less than or equal to 2 it is possible to easily obtain, nanotechnology such as the polymer is used in the fields of state of the art have been spotlighted as a method of manufacturing (for example, see Patent Document 1).
