Poly[phosphonate-co-carbonate] - 77226-90-5

Key Functions: Flame - Fire Retardants

This alternative is a polymer. Poly[phosphonate-co-carbonate] polymers differ in their ratio of polyphosphonate/polycarbonate (m to n) but would have identical hazard characterizations. The MW of the oligomers are generally >1,000 and are assessed together using the Sustainable Futures (SF) polymer assessment criteria (U.S. EPA, 2010).

Chemical Synonyms Carbonic acid, diphenyl ester, polymer with diphenyl P-methylphosphonate and 4,4'- (1- methylethylidene)bis[phenol]
