Abstract: A mineral-filled, polypropylene composition comprises (i) a coupled, impact propylene polymer, and (ii) at least 0.5 weight percent (wt %) based on the weight of the composition of at least one of calcium carbonate and talc. The compositions are useful in the manufacture of three-layer pipe comprising (A) a first or outer non-foam layer; (B) a second or middle foam layer; and (C) a third or inner non-foam layer.

Abstract: A method to join pipe is disclosed using a curable one or two part adhesive composition comprising an effective amount of a boron containing initiator compound such as an organoborate, a stabilized organoborane complex, or combinations thereof; one or more monomers, oligomers, polymers or mixtures thereof having olefinic unsaturation which is capable of polymerization by free radical polymerization; and optionally a decomplexing agent.

Abstract: A method to join pipe is disclosed using a curable one or two part adhesive composition comprising an effective amount of a boron containing initiator compound such as an organoborate, a stabilized organoborane complex, or combinations thereof; one or more monomers, oligomers, polymers or mixtures thereof having olefinic unsaturation which is capable of polymerization by free radical polymerization; and optionally a decomplexing agent. An especially preferred organoborane is one where a tertiary or quaternary nitrogen atom is bonded to the organoborane to prepare an amido-borate. In those embodiments where the nitrogen is quaternary, the quaternary nitrogen portion of the amido-borate is the cationic counter ion for the borate anion portion of the compound to which the quaternary nitrogen atom is bonded.

Abstract: The present invention is a amorphous saturated hydrocarbon thermoplastic substrate having enhanced adhesion properties, wherein the enhanced adhesion properties are obtained by treating the surface of the amorphous saturated hydrocarbon thermoplastic substrate with an excited gas phase technique, such that a critical surface energy of at least 35 dyne/cm is obtained without the use of acids or other corrosive materials which cause equipment degradation.

Abstract: A multilayered reflective body which is thermoformable and capable of being fabricated into a number of parts while maintaining a uniform reflective appearance is provided. The reflective polymeric body is formed from at least two diverse polymeric materials which differ in refractive index and which are arranged in substantially parallel alternating layers. The polymeric body is reflective in appearance yet is transparent or, colored if a coloring agent is included, upon illumination from a back light source. The polymeric body has application in variety of areas such as in an automobile lighting lens which is reflective and thereby indiscernible yet transmissive upon exposure to a back light source. Additionally, various parts of consumer appliances, for example a refrigerator door, can be formed from the polymeric body.
