Abstract:
1. A process for pelletizing a brominated aromatic polymer composition of the formula: wherein n is an average number in the range of about 2.9 to about 3.9, wherein each x is the same or different and is a whole number in the range of 3 to 5, the average number of all of the x′s in the composition being in the range of about 3.50 to about 3.80 and the weight percent of bromine as determined by X-Ray Fluorescence Spectroscopy in the polymer being in the range of about 73.4 to about 74.5, which process comprises forming a flowing melt consisting of a melt of a brominated aromatic polymer composition of the above formula; and either wherein, during the process of pelletization, formation of finely-divided particles and of air-entrainable dust is less than about 5 wt %.
