POROUS LAMINAR PELLETS OF WASTE POLY (ETHYLENE TEREPHTHALATE) FILM, AND PROCESSES FOR DRYING AND POLYMERIZATION

摘要

ABSTRACT OF THE DISCLOSUREPorous laminar pellets of comminuted crystallinepoly(ethylene terephthalate) waste film are formed. Thepellets do not contain a binder, but are coherent since thepolymer flakes making up the pellets are mechanicallyinterlocked or interwined. Rapid drying and solid statepolymerization rates are achieved, and the pellets havesufficient structural integrity to survive such processes,but may be readily disintegrated upon completion of suchprocesses if so desired. The pellets are also well adaptedfor dissolution, such as in glycol monomer for glycolysis,and in molten polymer.
