RECOVERY OF RECYCLABLE MATERIAL FROM A PHYSICAL COMBINATION OF IT AND NORMALLY SOLID POLY(ALKYLENE CARBONATE) MATERIAL

摘要

Disclosed is the recovery of normally solid recyclable material from a physical combination of it and normally solid poly(alkylene carbonate) by (1) subjecting a mixture of the combination and normally liquid hydroxy material to heat and pressure until the poly(alkylene carbonate) degrades to a liquid, and (2) separating the recyclable material from the liquid portion of the resulting mixture. Separation of lower molecular weight poly(alkylene carbonate), alkylene carbonate, or a mixture thereof from the liquid portion is disclosed also.
