PROPERTIES OF POLY (PROPYLENE CARBONATE) PRODUCED VIA SK ENERGY'S GREENPOL~(TM)TECHNOLOGY

摘要

Polypropylene carbonate (PPC) is an amorphous polymer made by alternating copolymerization of carbon dioxide and propylene oxide. SK Energy developed its own proprietary technology with a highly active catalyst for this copolymerization and has begun to produce PPC in its continuous process type pilot plant since late 2008 with a trade name GreenPol?. In this paper, we are describing the typical properties of PPC such as general physical properties, barrier properties, thermal and UV stability, and smoke density along with some rheological properties.
