Abstract

The present application pertains to a production method for a polymer, including a step for polymerizing a starting material composition (I) that includes: a monomer mixture (I-1) containing a macromonomer (a) represented by the following formula (1), and (b) a vinyl monomer; and 0.01 to 5 parts by mass of a non-metallic chain transfer agent with respect to 100 parts by mass of the monomer mixture (I-1); a polymer obtained by the production method; and a molded article. According to the present invention, there can be provided a polymer having exceptional resistance to dwell-induced degradation, and a molded article having exceptional yellowing resistance, a low haze value, and exceptional pliability.
