Title:
METHOD FOR SEPARATING DEGRADABLE POLYMER COMPOSITION
Document Type and Number:
Japanese Patent JP3512208
Kind Code:
B2
Abstract:

PURPOSE: To prevent a degradable polymer and a nondegradable polymer from mixing with each other in a process for recovering polymers.
CONSTITUTION: A fluorescent material is added to a degradable polymer compsn. to enable differentiation of the compsn. from a nondegradable polymer compsn. The fluorescent material added gives a degradable polymer an appearance under ultraviolet rays different from that of a nondegradable polymer. Thus, the degradable polymer is easily separated from the nondegradable polymer in a process for recovering polymers.
