Disclosed herein are carpets and carpet tiles comprising a primary backing material having a face and a back side; a plurality of fibers attached to the primary backing material and extending from the face of the primary backing material and exposed at the back side of the primary backing material; and an adhesive composition. The adhesive composition generally comprises at least one homogenously branched ethylene polymer. Also disclosed are methods for manufacturing the disclosed carpets and carpet tiles.

Homogeneously branched ethylene polymer carpet backsizing compositions

The present invention pertains to carpet and method of making it. In one aspect, the carpet includes (a) a primary backing which has a face and a back surface, (b) a plurality of fibers attached to the primary backing and extending from the face of the primary backing and exposed at the back surface of the primary backing, (c) an adhesive backing, (d) an optional secondary backing adjacent to the adhesive backing, and (e) at least one homogeneously branched linear ethylene polymer. The method includes extrusion coating at least one homogeneously branched linear ethylene polymer onto the back surface of a primary backing to provide an adhesive backing. The method can include additional steps or procedures, either separately or in various combinations. Additional steps and procedures include preheating the primary backing prior the extrusion step, multilayer adhesive backings, washing or scouring the primary backing prior the extrusion step, and utilizing adhesive polymeric additives, high heat content fillers, blowing agents and/or implosion agents. The constructions and methods described herein are particularly suited for making carpet tile.

Carpet, carpet backings and methods

The present invention pertains to carpet and methods of making carpet. In one aspect, the carpet includes (a) a primary backing which has a face and a back surface, (b) a plurality of fibers attached to the primary backing and extending from the face of the primary backing and exposed at the back surface of the primary backing, (c) an adhesive backing, (d) an optional secondary backing adjacent to the adhesive backing, and (e) at least one homogeneously branched ethylene polymer. The method includes extrusion coating at least one homogeneously branched ethylene polymer onto the back surface of a primary backing to provide an adhesive backing. The method can include additional steps or procedures, either separately or in various combinations. Additional steps and procedures include washing or scouring the primary backing and fibers prior to the extrusion step, and utilizing implosion agents. The preferred homogeneously branched ethylene polymer is a substantially linear ethylene polymer. The constructions and methods described herein are particularly suited for making tufted, broad-loom carpet having improved abrasion resistance.

Homogenously branched ethylene polymer carpet backsizing compositions

The subject invention is directed to a rheology-modified ethylene polymer having less than 0.5 weight percent gel, a composition distribution breadth index (CDBI) greater than 50 percent, and a molecular weight distribution (M /M ) of less than 4.0, which is characterized as having improved rheological performance and/or melt strength attributes relative to the unmodified polymer. The subject invention is further directed to polymer blends which comprise the rheology-modified polymers, and to a process for preparing the rheology-modified polymers.

Rheology-modified polyolefins

The subject invention is directed to a polyethylene composition comprising from about 5 to about 70 weight percent of a homogeneous ethylene/&agr;-olefin interpolymer, from about 30 to about 95 weight percent of at least one filler, and from about 0.1 weight percent to less than about 10 weight percent of at least one functionalized polyethylene. The polyethylene compositions of the present invention exhibit high tensile strength, high indentation resistance and filler holding capacity, and are especially useful for floor tile and sheeting applications.

Filled polyethylene compositions

Fibers made from &agr;-olefin/vinyl or vinylidene aromatic and/or hindered cycloaliphatic or aliphatic vinyl or vinylidene interpolymers

The present invention pertains to structures and fabricated articles having shape/reshape behavior (and processes for their preparation) comprising;

The subject invention is directed to a rheology-modified ethylene polymer having less than 0.5 weight percent gel, a composition distribution breadth index (CDBI) greater than 50 percent, and a molecular weight distribution (M.sub.w /M.sub.n) of less than 4.0, which is characterized as having improved rheological performance and/or melt strength attributes relative to the unmodified polymer. The subject invention is further directed to polymer blends which comprise the rheology-modified polymers, and to a process for preparing the rheology-modified polymers.

Compositions having good low temperature impact performance made from a thermoplastic (e.g., a polyolefin such as polypropylene) and either at least one linear ethylene/C.sub.5 -C.sub.20 .alpha.-olefin or at least one substantially linear ethylene/C.sub.3 -C.sub.20 .alpha.-olefin polymer are disclosed. The compositions are easily molded and have particular utility in making automotive facia, parts and other household articles.

Impact modification of thermoplastics

This application relates to flexible gaskets formed from blends of linear or substantially linear homogeneously branched ethylene/.alpha.-olefin interpolymers and that possess improved processability as well as low temperature resistance and resistance to staining and attack by microbes. Such gaskets do not require formulation other than the addition of color, to produce a functional product. The gaskets of the present invention do not impact negatively on the environment and are also relatively inexpensive to produce.
