    摘要： Sheet materials suitable for use as a floor, wall or ceiling covering material are described which comprise (1) a polymer mixture having (A) at least one homogeneously branched ethylene Polymer (A) having a molecular weight distribution, Mw/Mn, less than 3 and a short chain branching distribution index (SCBDI) equal to or greater than 50 percent obtainable by polymerization of ethylene with at least one C3-C20 α-olefin in the presence of a single site or constrained geometry catalyst; (B) at least one ethylene Polymer (B) having a density at least 0.005 g/cm3 greater than the density of ethylene Polymer (A) and a TREF elution temperature at least 5 °C greater than the TREF elution temperature of ethylene Polymer (A) and, optionally, (C) at least one ethylene Polymer (C) having a density at least 0.005 g/cm greater than the density of ethylene Polymer (B) and a TREF elution temperature at least 5 °C greater than the TREF elution temperature of ethylene Polymer (B), and (2) optionally a filler at least partially dispersed with a compatibilizer in the polymer mixture, and when less than 10 wt.% filler is dispersed in the polymer mixture, then the melt index of Polymer (A) is preferably less than or equal to 1.5g/10 min., the melt index ratio of Polymer (B) to polymer (A) is preferably less than or equal to 5.0, and/or Polymer (B) is preferably a homogeneously branched ethylene polymer. Floor, wall and ceiling covering materials and processes for making them according to this invention are also described.

    摘要： The subject invention provides a flexible, protective, integral liner comprising at least one first polymer which is a homogeneous linear or substantially linear ethylene/α-olefin interpolymer having a density of from 0.850 g/cm3 to 0.920 g/cm3, and at least one second polymer which is an ethylene/α-olefin interpolymer having a density of from 0.905 g/cm3 to 0.935 g/cm3, provided that the density of the second polymer is at least 0.002 g/cm3 greater than the density of the first polymer. In preferred embodiments, the liner will further comprise an ignition resistance additive. The liners of the invention exhibit an excellent balance of flexibility and strength, and, when an ignition resistance additive is employed, excellent ignition resistance.
