Process for Extracting Polyester from an Article

摘要

A process for extracting polyester from an article using a solvent system comprising a compound according to any of general Formula I to VI wherein R1 and R2 are each independently selected from: hydrogen, alkyl, alkenyl, alkynyl, aryl or alkoxy groups; R3 to R12 are each independently selected from: hydrogen, alkyl, alkenyl, alkynyl, aryl or alkoxy groups; X is selected from O or S; and each of a to e is a carbon atom, wherein the total linear chain length of a-b-c-d-e is in the range of 2 to 5 carbons; R13 and R15 are both independently aryl groups; R14, R16, R17, R18 and R19 are each independently selected from hydrogen, alkyl, alkenyl, alkynyl or aryl groups; n is an integer in the range of 1 to 8; m is 3; and 1 is an integer in the range of 1 to 3; or combination thereof.;
