ABSTRACT:
Three dimensional molded articles comprising liquid crystalline polyesters are recognized to be extremely difficult to finish such as by printing, painting, metallizing, plating, etc. An effective answer to this difficulty is provided by initially blending within the liquid crystalline polyester at least one particulate inorganic filler selected from the group consisting of Group II elements of the periodic table and oxides, sulfates, phosphates, silicates, and carbonates thereof, and elements of aluminum, silicon, tin, lead, antimony, and bismuth and oxides thereof, in an amount of 5 to 80 percent by weight; forming a molded article from the same; and contacting the resulting molded article with an acidic solution containing at least 80 percent by weight of sulfuric acid. The requisite surface modification for finishing to form a quality product is made possible.
