摘要： The disclosure aims to provide a modified polymer having excellent antifouling properties. The disclosure relates to a modified polymer including (a) a main chain containing a fluorine-containing polymer and (b) a side chain represented by the following formula (b1') and/or a side chain represented by the following formula (b2'). The formula (b1') is -CH 2 -CR b1 (-X)-C(=O)-Y-Z-Rf, wherein X is a hydrogen atom, a methyl group, or a halogen atom; Y is -O- or -NH-; Z is a direct bond or a divalent organic group; Rf is a C1-C20 fluoroalkyl group; and R b1 is a hydrogen atom or a monovalent organic group. The formula (b2') is -CH 2 -CR b2 (-R 1 )-C(=O)-O-Si(-CH 3 ) 2 -[O-Si(-CH 3 ) 2 ] n -O-Si(-CH 3 ) 2 -R 2 , wherein R 1 is a hydrogen atom or a methyl group; R 2 is a hydrogen atom or a methyl group; R b2 is a hydrogen atom or a monovalent organic group; and n is 3 to 200.

摘要： Provided is a coating composition that can enables to form a coating film having an excellent antifouling property using a fluorine-containing polymer having repeating units derived from (a) a fluorine-containing monomer, (b) a fluorine-free non-crosslinkable monomer, and (c) a fluorine-free crosslinkable monomer, wherein the fluorine-containing monomer (a) is a compound represented by formula: CH 2 =C (-X) -C (=O) -Y-Z-Rf ... (a-I) wherein X is a hydrogen atom, a monovalent organic group or a halogen atom, Y is -O- or -NH-, Z is a direct bond or a divalent organic group, Rf is a fluoroalkyl group having 1 to 20 carbon atoms, and wherein the fluorine-free non-crosslinkable monomer (b) comprises (b1) a cyclic hydrocarbon group-containing monomer and (b2) a low Tg monomer, a homopolymer of which has a glass transition temperature (Tg) of lower than 0°C.
