Key statements polymer having a carbon-carbon double bond in a main chain is decomposed by subjecting the carbon-carbon double bond to oxidative cleavage using an oxidizing agent such as periodic acid to decrease the molecular weight, polymer chains of the decomposed polymer are combined by changing acido-basic properties such that a system containing the decomposed polymer becomes basic when acidic and becomes acidic when basic, and a modified polymer in which the structure has been changed is obtained.
