Abstract
Polycarbonates, such as bisphenol A polycarbonates, having end groups derived from a di-t-alkylphenol such as 3,5-di-t-butylphenol have very low electrostatic charges. They are thus useful in applications where static charge is a problem, such as automotive headlamps and optical data recording media.
