摘要： A polycarbonate film having improved flame resistance and good stress-corrosion-cracking resistance is prepared from a solution of a mixture of a low molecular weight polycarbonate containing at least about 5% by weight halogen and a higher molecular weight polycarbonate prepared from bisphenol containing at least 90 mol percent bisphenol A. The novel film can be used to advantage for self-supporting electrical insulating films.
