Hyperbranched polymer, process for producing same, and composition

A method for producing a hyperbranched polymer, the method comprising the step of:

• reacting monomers with each other, the monomers comprising:
• a monomer (X) containing three or more hydroxy groups per molecule;
• and
• a monomer (Y) containing two or more groups represented by General Formula (y) per molecule, General Formula (y) expressed as follows:
• wherein Rγ1 is selected from hydrogen and C1-C16 alkyl;
• and Rγ2 and Rγ3 are each, identically or differently, selected from hydrogen, alkyl, and cycloalkyl, where at least two of Rγ1, Rγ2, and Rγ3 may be linked to each other to form a ring with adjacent one or two carbon atoms,
• the monomer (X) comprising 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),
• the monomer (Y) comprising a compound represented by General Formula (1),
• General Formulae (I), (II), (III), (IV), and (1) expressed as follows:
• wherein p is selected from 1, 3, and 5;
• q represents, identically or differently in each occurrence, an integer of 1 to 3;
• and Ra is, independently in each occurrence, selected from hydrogen, C1-C4 alkyl, and t-butylphenyl,
• wherein Rb is, identically or differently in each occurrence, selected from hydrogen and alkyl, where at least three occurrences of Rb are hydrogen atoms,
• wherein Rc is, identically or differently in each occurrence, selected from hydrogen and alkyl, where at least three occurrences of Rc are hydrogen atoms;
• and r represents, independently in each occurrence, an integer of 1 to 4,
• wherein Rd represents, identically or differently in each occurrence, alkyl;
• and Re is, identically or differently in each occurrence, selected from hydrogen and alkyl, where at least three occurrences of Re are hydrogen atoms,
• wherein R1 is selected from hydrogen and C1-C16 alkyl;
• R2 and R3 are, identically or differently in each occurrence, selected from hydrogen, alkyl, and cycloalkyl, where at least two of R1, R2, and R3 may be linked to each other to form a ring with adjacent one or two carbon atoms;
• X1 represents an m-valent organic group;
• and m represents an integer of 2 or more, where occurrences of the group in the brackets with “m” may be identical to or different from each other.
