Abstract:
1. A hyperbranched polymer represented by Formula (5): where a branched repeating unit structure in Formula (5) has a structure of a branched repeating unit represented by Formula (4) in which A 1 represents Formula (2) and a branched repeating unit represented by Formula (4) in which A 1 represents Formula (3) are coupled to each other, with the proviso that R 1 in Formula (4) in which A 1 represents Formula (2) and R 1 in Formula (4) in which A 1 represents Formula (3) may be the same as or different from each other, wherein the hyperbranched polymer has a weight average molecular weight of 500 to 5,000,000, as measured by a gel permeation chromatography in a converted molecular weight as polystyrene.
