Abstract: A thixotropic gel composition is disclosed as a fiber optic buffer tube compound. The composition as a fiber optic buffer tube compound is resistant to syneresis and phase separation, and to ingress of water and water vapor. The composition has low temperature flowability at -40.degree. C. as determined by a cone penetration test and has continued high temperature consistency at +80.degree. C. The composition retains its low temperature flowability property after a heat aging test at 93.degree. C. The composition comprises polybutene, polyethylene wax, hydrophobic fumed silica, and, optionally, an antioxidant.

Abstract: A water-based wax-free stable emulsion composition, useful as water sealer for wood, concrete and porous materials is disclosed. The water-based sealer composition forms a non-drying film that is water-repellant, flexible, self-sealing and allows passage of water vapor. The water-based sealer composition contains less than 400 grams per liter of volatile organic compounds. The water-based sealer composition is especially suited for above-grade applications in that it protects against absorption of water.

Abstract: A modified propylene polymer composition of improved low temperature impact resistance comprising about 55 to about 80 weight percent polypropylene homopolymer, about 15 to about 30 weight percent linear low density polyethylene and about 5 to about 15 weight percent polybutene.
