AMORPHOUS COPOLYESTER COMPOSITIONS CONTAINING CARBON BLACK

摘要

This invention relates to a blend comprising: (a) one or more substantially amorphous copolyester resins having a degree of crystallinity of less than 20 percent; (b) from about 5 to about 25 weight percent carbon black; and (c) from about 7 to about 30 weight percent of an impact modifier, wherein the total of the weight percentages of (a), (b), and (c) equals 100 percent. This invention is advantageous in that it provides the advantages of good electroconductivity, lack of brittleness, ability to thermoform into desired shapes, good impact strength, good sealing characteristics and acceptable environmental image.
