Abstract
It is an object of the present invention to provide a method for obtaining a resin composition in which coloration is suppressed. According to an embodiment, provided is a method for producing a resin composition, including: (a) obtaining a resin by polymerization of a resin raw material containing a compound represented by formula (1) below and (b) obtaining a resin composition by mixing an additive into the resin, wherein a polymerization temperature T1 in step (a) falls within the range of 230° C.<T1<250° C., and a mixing temperature T2 in step (b) falls within the range of 250° C.≤T2<280° C.
