    • The present invention provides a copolymer for syrup, characterized by being formed from (A) 1 to 60 mass% of at least one (meth)acrylate compound selected from among a (meth)acrylate-modified silicone oil, an alkyl (meth)acrylate, a monoalkylene glycol (meth)acrylate, and a polyalkylene glycol (meth)acrylate, and (B) 99 to 40 mass% of a (meth)acrylate compound having a C≥6 alicyclic hydrocarbon group bonded thereto via an ester bond; a (meth)acrylate composition containing a (meth)acrylate monomer and 1 to 60 mass% of the (meth)acrylate copolymer for syrup; and a cured product of the composition. The (meth)acrylate copolymer for syrup of the present invention has excellent solubility, particularly in a (meth)acrylate compound having an alicyclic ester substituent, and a (meth)acrylate resin composition containing the copolymer provides a stable cured product having high transparency and high resistance to UV rays and heat. Thus, the cured product is suitably used as a material for lenses, illumination devices, automobiles, displays, optical-semiconductors, etc.
