Title:
SEPARATION/COLLECTION METHOD FOR RESIN MIXTURE
Document Type and Number:
WIPO Patent Application WO/2022/265112
Kind Code:
A1
Abstract:
A separation/collection method is provided in which a hydrolyzate a of a hydrolyzable polymer A and a non-hydrolyzable polymer B are separated and collected from a mixture at least including a resin layer 1, which comprises the hydrolyzable polymer A as a main component, and a resin layer 2, which comprises the non-hydrolyzable polymer B as a main component. The separation/collection method includes a decomposition/separation step in which the mixture is subjected to a hydrothermal reaction treatment to hydrolyze and separate the hydrolyzable polymer A and, simultaneously therewith, the non-hydrolyzable polymer B is separated with the molecular weight unchanged.
