Abstract
A method is provided for the production of a powder comprised of particulates of a liquid crystal polymer. The powders of such polymers are uniquely suited for use in temperature and chemical resistant coatings. The particulates are formed by providing foamed articles of liquid crystal polymers and subsequently masticating the articles to form the desired particulates.
Claims26
A method of providing particulates of a polymer which is capable of forming an anisotropic melt phase and suitable for use in a thermally and chemically resistant coating which method comprises providing a foamed melt of said polymer, forming an article comprised of said polymer which contains a multitude of voids, and masticating said article to an extent sufficient to form particulates of said polymer.
