RECYCLABLE POLYMERS, PROCESSES FOR THEIR PRODUCTION, AND RECYCLING PROCESS

摘要

A novel resin is provided which is renewable with less energy. A process for renewing the resin is also provided. The present invention includes: A polymer having the repeating unit represented by Structural Formula (1) below, and a process for producing the polymer: Ä-P1-R-Ün (in the formula, P1 indicates an addition polymer moiety having a continuous hydrocarbon chain as the skeleton containing no condensation system, and is a polymer or oligomer prepared by addition polymerization of one or more monomers having a double bond; R indicates a linking group constituted of a condensation system for linking the polymer moieties P; and n is a number of repeating units and is an integer of 2 or more); A polymer composition containing the aforementioned polymer (A) and a compound (B) having a condensable functional group and a spin-trapping group; and a process for production thereof; A treatment method for depolymerizing the polymer selectively at the linking group R in the Structural Formula, and a treatment method for recycling the polymer by the depolymerization and recondensation.
