Solid Polymer Derived From Ethylenically Unsaturated Hydrocarbon Only Patents (Class 524/274)
  • Patent number: 6890982
    Abstract: Waxes prepared from hydrogenated plant oils, such as palm and soybean, are used as substitutes for petroleum derived waxes in hot-melt adhesive compositions. Unlike petroleum-derived or synthetic waxes, adhesive compositions comprising these waxes, which are obtained from naturally derived, renewable resources, achieve adhesion performance similar to conventional adhesives containing petroleum-derived waxes. The inventive waxes have a low iodine value (between 2-5), and melting points between approximately 120-165 degrees F. (Mettler Drop Point). These waxes comprise a triglyceride whose fatty acids are predominantly stearic acid (C18). The naturally derived waxes are used as an alternative to petroleum and synthetically derived waxes in the manufacture of adhesives used to bond paper, wood, glass, plastic and metal in a variety of manufacturing operations.

The repair composition is a physical mixture of a thermoplastic powder, a resin binder, and a solvent, having a paste-like consistency. The repair composition may be neutral in color, or may contain a colorant to closely match the underlying object. The heating step can be performed with an open flame or with a heat gun.

  • Patent number: 6274657
    Abstract: A surfactant for forming stable dispersions of rosin esters compatible with elastomeric latexes, the surfactant having the formula R1—R2—R3. R1 and R3 are each rosin (i.e., rosin, rosin dimer or a mixture of rosin and rosin dimer). R2 is selected from the group consisting of polyethylene glycol and polyethylene glycol-R4-polyethylene glycol wherein R4 is rosin (i.e., rosin, rosin dimer or a mixture of rosin and rosin dimer). The surfactant is prepared by esterifying the rosin material with polyethylene glycol.

  • Patent number: 6258885
    Abstract: A filling compound for electrical and optical equipment in the form of cables, connectors, plugs, etc. and to assemblies thus produced, is provided. Electrical and optical equipment in the form of cables, connectors, plugs, etc. have to be protected against harmful influences penetrating from outside, particularly water, and also against mechanical damage during laying or as a result of exposure to heat. The filling compound is based on a stellate substance, i.e. a substance having a branched molecular structure in which, ideally, 3 or more branches, more particularly polymeric chains, radiate from a single branching point. The filling compound is flexible at very low temperatures but, on the other hand, does not run out, even at extremely high temperatures.

  • Patent number: 6214935
    Abstract: An improved hot-melt pressure-sensitive adhesive (HMPSA) composition contains an elastomeric component, such as a blend of SIS and SB block copolymers, and a tackifying component comprising one or more intermediate softening point resins (ISPRs) having a ring and ball softening point of from 35 to 60° C. The improved adhesive compositions are characterized by reduced volatility, less bleed and staining tendencies, and improved overall adhesive performance. The invention also provides improved label constructions in which a release liner is coated with an HMPSA composition and laminated to a flexible facestock. Notably, even when low basis weight paper facestocks are used, the construction can be converted at high speeds.
