The aim of the present invention is to provide a multi-branched polymer, in which branch terminals can be easily modified and which have a high degree of branching and narrow dispersion. By polymerizing a compound having 2 or more polymerization-initiation sites and polymerizable unsaturated bonds with a living radical polymerization method using a metal catalyst, it is possible to produce a multi-branched polymer with narrow dispersion and a high degree of branching and having repeating units represented by the formula (I): wherein Rto Reach independently represents hydrogen or a hydrocarbon group, Rmay be bonded to Rto form a ring; X represents a connecting group having a valence of 3 or higher; Y may be the same or different and each represents a functional group which may have a halogen atom at a terminal thereof; and a is an integer of 2 or larger.

Multi-branched polymer

The present invention provides a polymer solid electrolyte excellent in thermal properties, physical properties and ion conductivity and being close to practical level; especially, a totally solid electrolyte and a composition for producing the same. A composition for polymer solid electrolyte includes a copolymer having repeating units represented by Formula (I): (wherein each of Rto Rindependently represents a hydrogen atom or a C1-C10 hydrocarbon group; Rand Rindependently represents a hydrogen atom or a methyl group; Rrepresents a hydrogen atom, a hydrocarbon group, an acyl group or a silyl group; and m is an integer of 1 to 100), and repeating units represented by Formula (II): (wherein each of Rand Rindependently represents a hydrogen atom or a C1-C10 hydrocarbon group; Rrepresents an organic group having at lease one functional group selected from the group consisting of hydroxyl group, carboxyl group, epoxy group, acid anhydride group and amino group); and an electrolyte salt.
