    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 (S101). 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 (S102). The first monomer in the addition amount determined is then mixed with the polymer material (S103).

    Abstract: The proposed method of chemical recycling of polyethylene terephthalate waste to terephthalic acid and ethandiol is based on a continuous series of gradual steps, namely (a) separation of the polyethylene terephthalate component of the input material by its conversion to brittle form through crystallization, grinding and subsequent sifting, followed by (b) continuous two-stage hydrolysis of the polyethylene terephthalate, carried out in the first stage by feeding steam to the polymer melt, and in the second stage, by the reaction of the products of the first stage of hydrolysis with ammonium hydroxide, followed by (c) condensation of terephthalic acid from an aqueous solution of the second-stage hydrolysis products by inorganic acid, and its separation by means of filtration, and finally (d) rectification separation of ethandiol from a solution of the products of the second stage of hydrolysis, after the separation of terephthalic acid.
