Abstract
The present invention is a method for decomposing a polymer material by chemically decomposing a polymer material containing a first monomer and a second monomer in a mixture of the polymer material with the first monomer or a derivative of the first monomer to produce a chemical raw material. A relationship between a proportion of number of molecules of the second monomer to number of molecules of the first monomer in a reaction system for decomposing the polymer material and the molecular weight of the chemical raw material produced in the reaction system is acquired in advance (S). Subsequently, an addition mount of the derivative of the first monomer to be added to the polymer material is determined based on the above relationship (S). The first monomer in the addition amount determined is then mixed with the polymer material (S).
