    摘要: It has now been surprisingly found that addition of a phosphorous-containing oxy acid to a glass-filled polycarbonate composition substantially improves its fire retardant performance. Thus, the present invention provides a method for making a flame-retarded glass-filled polycarbonate resin comprising adding to the resin an effective flame-retardant amount of a phosphorous-containing oxy acid. Where appropriate, the melt strength of the polycarbonate is enhanced by the addition of an antidrip agent and the performance can be further enhanced by the addition of a flame retardant. Use of such a composition results in superior fire-retardant performance.

    摘要: A thermoplastic composition comprising in combination a dialkyl bisphenol polycarbonate homopolymer or copolymer comprising repeat carbonate units having the following structure; wherein R1 and R2 are independently at each occurrence a C1-C4 alkyl, n and p are each an integer having a value of 1 to 4, and T is selected from the group consisting of C5-C10 cycloalkanes attached to the aryl groups at one or two carbons, C1-5 alkyl groups, C6-C13 aryl groups, and C7-C12 aryl alkyl groups; a flame retardant; and an anti-dripping agent is disclosed. The compositions have excellent scratch resistance as well as an improved balance of physical properties such as melt flow, while at the same time maintaining their good flame performance.
