Title:
HYPERBRANCHED POLYMER, PROCESS FOR PRODUCING SAME, AND COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2016/035491
Kind Code:
A1
Abstract:
Provided is a hyperbranched polymer in which the main chain can be easily decomposed by an acid. The hyperbranched polymer is obtained by reacting one or more monomers (X) each having three or more hydroxy groups in the molecule with one or more monomers (Y) each having, in the molecule, two or more groups represented by general formula (y), and is characterized in that the monomers (X) comprise at least one compound selected from the group consisting of cyclodextrins, compounds represented by general formula (I), pillararenes, compounds represented by general formula (II), compounds represented by general formula (III), and compounds represented by general formula (IV) and the monomers (Y) comprise a compound represented by general formula (1).
