  • Publication number: 20140094762
    Abstract: Disclosed herein are novel stabilizers for thermoplastic oil-modified alkyd resins. It has now been found that such stabilizers can greatly increase the stability of alkyd resins against melt viscosity variations after thermal aging. The alkyd resins can be used as the predominant component of a hot melt adhesive which can be employed for instance as a construction adhesive in the manufacture of disposable absorbent articles.

  • Publication number: 20110245430
    Abstract: A hot melt adhesive is disclosed that contains 3-35% by weight of one or more styrene block copolymers, more than 25% and less than 60%, by weight, of triglycerides of fatty acids with an average carbon chain length distribution from C14 to C20 and a iodine value lower than 50; and 5-70% by weight of a tackifier or blend of tackifiers selected from terpenic tackifiers, rosin tackifiers and rosin ester tackifiers. This hot melt adhesive can be applied at low temperature and has very low tack when cold.

  • Publication number: 20100063173
    Abstract: An adhesive composition is described that is particularly useful for application to the plastic nonwoven materials found in personal hygienic articles. The composition includes first and second ethylene vinyl acetate copolymers. The first copolymer has a high molecular weight characterized by a melt viscosity at 150° C., of 100 Pascals per second or more. The second copolymer has a low molecular weight characterized by a melt viscosity at 150° C. of 50 Pascals per second or less. The second copolymer is present in an amount by weight percent less than or equal to the amount by weight percent of the first ethylene vinyl acetate copolymer. The composition also includes at least one tackifier resin, a hydrocarbon wax present in an amount from 0.5% to 10% by weight of the composition; and, a liquid plasticizer present in an amount up to 20% by weight of the composition.

  • Publication number: 20040180998
    Abstract: The present invention relates to hydrophilic polymeric compositions for making a liquid impermeable moisture vapour permeable structure, for example by forming the composition into a layer or coating onto a suitable substrate for example a microporous film and to composite structures comprising the compositions. The hydrophilic polymeric compositions of the present invention do not solidify at room temperature, but remain viscous or “creamy”. This prevents layers made from the hydrophilic polymeric composition of the present invention from settling as a film so that delamination of a composite structure comprising the hydrophilic polymeric composition coated into a layer onto a suitable substrate is avoided. The hydrophilic polymeric compositions of he present invention can find a variety of applications wherein liquid imperviousness and moisture vapour permeability are desirable.
