  • Aqueous polymeric emulsion compositions
    Patent number: 6620878
    Abstract: A pourable liquid composition comprising water, a water soluble or water swellable organic polymer, comprising 25 to 90 mole % monomer or monomers selected from the group consisting of C8-C30 alkyl ethoxylated (meth)acrylates, C8-C30 alkyl ethoxylated (meth)acrylamides, C8-C30 alkyl (meth)allyl ethers and C8-C30 alkyl ethoxylated (meth)allyl ethers, an organic water miscible liquid selected from the group consisting of C1-5 alcohols, C3-5 ketones, C2-5 esters and C2-5 ethers, characterized in that the organic polymer is present as discrete particles of average diameter size of below 10 microns. A process of imparting water resistance to the components of a cable said process by first contacting one or more of said components of a cable with said pourable liquid composition, and then assembling the components to form the cable. The composition is particularly suitable for protecting optical fibers within a fiber optic cable against the ingress of water.
