[Problem] A copolymer of a monomer containing triisopropylsilyl (meth)acrylic acid and a (meth)acrylic acid derivative capable of producing a coating composition that lowers the viscosity as much as possible and reduces the amount of organic solvent used compared to the prior art, and a method for producing the same to provide. [Solutions] It is a copolymer of (meth)acrylic acid triisopropylsilyl represented by the following general formula (1) and a monomer containing a (meth)acrylic acid derivative, and has a number average molecular weight of 6,000 to 100,000, and a molecular weight distribution ( Mw/Mn) of 2.0 or less.
