Definitions

  • the article states that the addition of fluoropolymer is required to reduce die build-up, and teaches that the addition of a low molecular weight wax or products containing a low molecular weight wax may actually increase the formation of die build-up and other surface problems.
  • U.S. 4,650,747 teaches a masterbatch containing 40- 80% coated or uncoated anatase or rutile to let down for photographic paper coating.
  • the use of Zn, Ca, Mg, Al, and Zr stearates, sodium palmitate, or sodium laurate is noted. It is also taught that the use of greater than 500 ppm (0.05%) of an antioxidant caused dye stains and microgrits; U.S.
  • the compositions contain at least one polyolefin (most preferably polyethylene) and one or more coated or uncoated pigments such as titanium dioxide or zinc oxide, and further comprise a sulfur containing phenolic antioxidant, such as Santonox®, in combination with a sulfur-containing ester, such as DSTDP (distearyl thiodipropionate) or Seenox® 412S.
  • a sulfur containing phenolic antioxidant such as Santonox®
  • a sulfur-containing ester such as DSTDP (distearyl thiodipropionate) or Seenox® 412S.
  • Optional ingredients include other stabilizers, such as phosphites, and other fillers and pigments such as talc or calcium carbonate.
  • preferred but optional additives include one or more of slips, such as PETS (pentaerythritol tetrastearate) , mono-amides, such as erucamide or stearamide, bis-amides, such as Kemamide® W-40, fatty acids, such as stearic acid, phosphorus-containing stabilizers (such as Irgafos® 168 or Ultranox® 626) .
  • slips such as PETS (pentaerythritol tetrastearate)
  • mono-amides such as erucamide or stearamide
  • bis-amides such as Kemamide® W-40
  • fatty acids such as stearic acid
  • phosphorus-containing stabilizers such as Irgafos® 168 or Ultranox® 626
  • Other optional additives include other fillers and pigments such as talc or calcium carbonate.
  • stearic acid When vapor lines appear, it has been found that the problem may be solved by adding, in a preferred embodiment, stearic acid.
  • Other long-chain acids may be used, preferably those having 8 or more carbon atoms.
  • metal stearates and metal salts of other long chain acids tackifying resins such as terpene- phenol resins, PEG waxes (those having a molecular weight of from about 600 to about 10,000), polyethylene waxes having carboxylic functionality such as olefin/maleic copolymers and oxidized polyolefins (e.g., those available from Eastman Chemical Company, Kingsport, TN) , poly (vinyl alcohol), or more generally materials such as those enumerated having a polar end and a "fatty" segment, e.g., 8 or more carbon atoms, preferably C8-C22, may be used.
  • the vapor line problem can be solved by the use of alkali metal stearate
  • the polyethylene concentrate from Example 1 was pellet blended with natural LDPE pellets (density 0.924 g/cc; melt index 4.2 g/10 min.) at a ratio of 1:2 and the blend dried at 180°F for 12 hours in a desiccant bed dryer.
  • the extruder was operated with extruder temperature settings ranging from 560°F at extruder zone 1 up to 595°F for zone 5.
  • the adapter temperature was 595°F and the die was set at 580°F.
  • the melt temperature coming from the die was 620-640°F.
  • the predicted L* is 93.9. Increasing Ti0 2 to 20 weight percent at the same coating weight, the predicted L* is 95.
  • the model predicts that it would take a coating thickness of 25.3 to achieve the same L* with 10 weight percent Ti0 2 which would require 25% more Ti0 2 and also result in thicker coated paper. This also can have a negative impact if the paper is intended for a personal computer printer where feeding paper to the printer is dependent on thickness.
  • Another advantage of being able to coat a higher loading of Ti0 2 at a reduced thickness is that paper that is less bright can be used (less bleaching of the pulp) and the Ti0 2 can do the work to achieve the final L* .
  • a preferred embodiment of the present invention is a polyolefin composition having stabilizers and/or chill roll release agents/slip additives and in the essential absence of A1-, Mg-, or Ca-containing metal soaps.
  • essential absence of Ca-, Mg- or Al-containing metal soaps is meant that less than 0.5 weight percent of the aforementioned metal soaps are present.
