Polycarbonate containing a bis(cyclic phosphate) as a thermal stabilizer

摘要

A polycarbonate such as a bisphenol-A homopolycarbonate containing a small amount of an aromatic bis(cyclic phosphate) such as 2,2'-[(1-methylethylidene)bis(4,1-phenyleneoxy-2,1-ethanediyloxy)]bis( 5,5-dimethyl-2,2'-dioxo-1,3,2-dioxaphosphorinane) exhibits improved thermal stability.
