摘要： Provided is a low-odor polymer which is soluble in a solvent and with which a work environment load can be reduced. In addition, provided are a curable composition using the polymer and a cured product of the curable composition. The vinyl-based polymer of the present invention comprises a terminal structure derived from one or more of 3- to 20-mer of a (meth)acrylic monomer, wherein an acid value is 35 to 300 mgKOH/g.
