  • Patent number: 8367772
    Abstract: A crosslinked aramid polymer comprising a first aramid backbone which is crosslinked through a poly(meth)acrylic acid with a second aramid backbone. The crosslinked aramid polymer is obtained by polymerizing a monomeric aromatic diamine with a monomeric aromatic diacid, or halide or ester thereof in the presence of poly(meth)acrylic acid, followed by a curing step. The crosslinked aramid polymer is crosslinked through its amide bonds and can be made to a fiber, film or fibrid.

  • Publication number: 20120245238
    Abstract: The invention relates to a composition that has been obtained by the melt-process recycling of one or more multi-layer articles, where the multi-layer articles are composed of at least one melt-processible fluoropolymer layer. The composition of the invention is a compatible blend of the different layers from the multi-layer articles. The other layers of the multi-layer articles are also melt-processible, and include one or more layers chosen from: a) a melt-processible fluoropolymer of a different composition, b) a non-fluoropolymer, and c) a barrier layer. The composition is useful for forming an article in a melt-process operation. The composition may be used by itself, may be blended with other virgin or recycled materials, or may be used at low levels with melt-processible polymers as a process aid.
