METHOD FOR DECOMPOSING POLYMER CONTAINING URETHANE LINKAGE AND/OR UREA LINKAGE

摘要

In the decomposition of a polymer containing a urethane linkage and or urea linkage in the presence of a decomposing agent, the amount of evolved carbon dioxide is measured and the decomposition reaction is conducted until a total amount of evolved carbon dioxide reaches a specified value to obtain a liquid decomposition product. According to the present invention, a decomposition product having constant quality can be obtained in a simple manner.
