PURPOSE:To obtain the subject polymer having excellent photo-setting property and reactivity and useful for adhesive, etc., by carrying out radical copolymerization of a specific (meth)acrylate monomer and a specific mono(meth)acrylate monomer at a prescribed ratio under specific condition. CONSTITUTION:The objective polymer can be produced by the radical copolymerization of (A) 60-0.5mol% of a (meth)acrylate monomer expressed by formula I [R is H or methyl; R2 is group containing (meth)acryloyl group], having a molecular weight of <=700 and containing plural (meth)acryloyl groups and (B) 40-99.5mol% of a mono(meth)acrylate monomer expressed by formula II (R1 is 6-22C alkyl, cycloalkyl, etc.), having a molecular weight of >=160 and containing one (meth)acryloyl group in a good solvent of the mono(meth)acrylate monomer at a total monomer concentration of <=2mol per 1l of the system.
