METHOD FOR DECOMPOSING POLYMER MATERIAL, PROCESS FOR PRODUCING REPROCESSED RESIN, AND METHOD FOR RECOVERING INORGANIC FILLER

Document Type and Number:

WIPO Patent Application WO/2010/029733

Kind Code:

A1

Abstract:

Disclosed is a method for decomposing a polymer material, comprising subjecting a mixture of a polymer material comprising a first monomer and a second monomer with a first monomer or a derivative of the first monomer to decomposition to chemically decompose the polymer material and thus to produce a chemical starting material. A relationship between the proportion of the number of moles of the second monomer to the number of moles of the first monomer in a reaction system for decomposing the polymer material and the molecular weight of the chemical starting material produced in the reaction system is previously acquired (S101). Subsequently, the amount of the derivative of the first monomer to be added to the polymer material is determined based on the above relationship (S102). The first monomer in the determined addition amount is then mixed with the polymer material (S103).
