    Abstract: Compositions based on polycarbonate copolymers to provide ultra-clean materials and articles useful in the hard disk drive and semiconductor industries. In one aspect, the compositions include a polycarbonate copolymer based on a sebacic acid, BPA, PCP polyestercarbonate. The compositions may be used with or without other polymers, fillers or additives. The compositions based on this polycarbonate copolymer exhibit ultra clean performance, low organic contamination, low LPC, and low ionic contaminations. Meanwhile, the compositions also exhibit good flow ability, good ductility and good surface quality.
