The invention provides a crosslinked composition formed by thermally treating a composition comprising at least the following: A) an ethylene-based polymer that has a density less than, or equal to, 0.910 g/cc; B) an olefin-based polymer that has a melt viscosity less than, or equal to, 20,000 cP, at 350°F; and C) a crosslinking agent.
摘要:
A 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 olefin block copolymer, especially ethylene based block copolymers. An olefin block copolymer is extrusion coated onto the back surface of a primary backing to provide an adhesive backing. Additional steps and procedures can include washing or scouring the primary backing and fibers prior to the extrusion step, and utilizing implosion agents. The preferred olefin block copolymer is an ethylene based block interpolymer. The constructions and methods are suited for making tufted, broad-loom carpet having improved abrasion resistance.
