  • Non-woven application for water dispersable copolyester
    Patent number: 6448463
    Abstract: This invention relates to water responsive thermoplastic compositions and articles constructed thereof. This invention particularly relates to thermoplastic copolyester compositions useful for the manufacture of disposable-articles such as disposable diapers and feminine napkins. More particularly, this invention relates to thermoplastic copolyester compositions that are useful as a raw material in the manufacture of nonwovens, barrier films or coatings and as well as for various improved hot melt adhesives compositions useful for incorporating hydrophilic features into disposable articles.

  • Method for making hot melt adhesive pellet comprising continuous coating of pelletizing aid
    Patent number: 6238732
    Abstract: This invention relates to a hot melt adhesive composition in pellet form. The hot melt adhesive composition is pressure sensitive, having a storage modulus, G′, at 25° C., of less than about 5×106 dynes/cm2. The pellets are coated with a pelletizing aid on the surface at a concentration preferably ranging from about 1 wt-% to about 30 wt-%. The pelletizing aid is a hot melt adhesive component or a material which does not substantially adversely affect the adhesive properties.

  • Pressure sensitive adhesive comprising saturated backbone having side chains
    Patent number: 6166147
    Abstract: The present invention is a hot melt pressure sensitive adhesive comprising a block copolymer structure having an A--B--A backbone block copolymer having B or C blocks attached to the backbone, wherein the A--B--A block backbone is saturated and the B or C block is of the same composition or of a different composition than the midblock of the backbone.

  • Hot melt adhesive pellet comprising continuous coating of pelletizing aid
    Patent number: 6120899
    Abstract: This invention relates to a hot melt adhesive composition in pellet form. The hot melt adhesive composition is pressure sensitive, having a storage modulus, G', at 25.degree. C., of less than about 5.times.10.sup.6 dynes/cm.sup.2. The pellets are coated with a pelletizing aid on the surface at a concentration preferably ranging from about 1 wt-% to about 30 wt-%. The pelletizing aid is a hot melt adhesive component or a material which does not substantially adversely affect the adhesive properties. The pellets are free-flowing and have a substantially tack-free surface.
