摘要： The novel adhesives of this invention contain a blend of components that result in the adhesive having a physical property that changes at a controlled rate as a function of time after application until it reaches a final equilibrium value.The adhesives can contain a thermoplastic polymer base, a tackifying resin, and an aromatic plasticizer optionally in combination with other ingredients. The plasticizer tackifier combination is chosen such that the tackifier/plasticizer interaction causes the initial value of the physical property after application to change, at a controlled rate, to a final equilibrium level.

摘要： A lactide polymer composition combining compositional and purity limitations and catalyst optimization or addition of stabilizing agents resulting in a melt-stable polymer is disclosed. The melt-stable lactide polymer comprises a plurality of polylactide polymer chains, residual lactide in concentration of less than 2 percent and water in concentration of less than 1000 parts-per-million. A stabilizing agent in an amount sufficient to reduce depolymerization of the lactide polymer during melt-processing or alternatively, control of catalyst level at a molar ratio of monomer to catalyst greater than 3000:1 is also included in the melt-stable composition. A process for manufacture of a melt-stable lactide polymer composition includes polymerizing a lactide mixture and adding stabilizing agents sufficient to reduce depolymerization of the polylactide during melt-processing, followed by devolatilizing the polylactide to remove monomer and water.

摘要： Aqueous polyurethane dispersions used in adhesives for manufacturing laminate structures are provided with improved dispersion properties, which provide improved shelf-life stability of the dispersion and greater transparency and handling characteristics in application machinery for adhesives formulated therefrom, when a tertiary amine is present during an initial polyurethane prepolymer reaction between an isocyanate and a polyol component having acid functional groups. The initial reaction is carried out prior to formation of the dispersion in water.

摘要： Conjugate fibers are prepared in which at least one segment is a mixture of a high-D PLA resin and a high-L PLA resin. These segments have crystallites having a crystalline melting temperature of at least 200° C. At least one other segment is a high-D PLA resin or a high-L PLA resin. The conjugate fibers may be, for example, bicomponent, multi-component, islands-in-the-sea or sheath-and-core types. Specialty fibers of various types can be made through further downstream processing of these conjugate fibers.
