The present invention relates to a process for manufacturing a shoe rubber outsole using a special heat and pressure stable water-based polyurethane dispersion adhesive without a pre-treatment of UV irradiation or plasma, as well as a process for manufacturing a shoe using the outsole manufactured as described herein and an PUD-based adhesive composition for the described processes.

The present invention relates to a polyester consisting of (A) repeat units derived from an acid component, which consists of (a1) 2,5-furandicarboxylic acid, (a2) an aliphatic C.sub.4-C.sub.36 dicarboxylic acid or a mixture of a plurality of aliphatic C.sub.4-C.sub.36 dicarboxylic acids, and (a3) a sulfonate group-containing dicarboxylic acid, and of (B) repeat units derived from a di-ol/amine component, and optionally of further repeat units (C) and/or branching components (E), and of (D) repeat units derived from at least one di- or oligofunctional compound selected from the group consisting of a di- or oligoisocyanate and a di- or oligoisocyanurate. In addition, the present invention relates to the production of these polyesters and their use.

The invention relates to a thermally activatable reactive adhesive film comprising a carrier film made of thermoplastic polyurethane, which is coated on at least one side with a latently reactive, thermally activatable adhesive compound.

One-component heat-activatable polyurethane water-based adhesive composition, which comprises, with respect to the total weight of the adhesive composition: —from 12% to 50%, by weight of dry matter, of an aqueous dispersion of a polyurethane (A) comprising alkoxysilyl pending and/or terminal groups, and —from 0.5% to 5% by weight of a glycidoxy substituted alkoxysilane compound (B) with a glycidoxy functionality of at least 2.

There is provided herein a clear, transparent, low yellow color and non-yellowing moisture-curable silylated polymer composition, which contains an alkoxysilyl-containing polymer, a light stabilizer, a sterically hindered amine, a silicon compound containing a conjugated C═C group, an adhesion promoter and curing catalyst. There is also provide a method of making the moisture-curable composition and a sealant comprising the same.

A composite polyurethane condom and a preparation method thereof. The composite polyurethane condom includes a first substrate layer, an adhesive layer formed on the first substrate layer, and a second substrate layer formed on the adhesive layer. A special adhesive layer is added between the two layers of materials, so that, for example, two materials with different polarities can be firmly attached together without delamination.

The present invention relates to processes for the manufacture of aqueous polyurethane dispersions that can be used as adhesives or coatings, are solvent free and have low VOC emissions, and are environmentally friendly. Also encompassed are the dispersions as such, compositions containing them and their use as coatings and adhesives.

The present invention relates to an aqueous emulsion including an ethylenically unsaturated monomer unit-containing polymer as a dispersoid and a polyvinyl alcohol as a dispersant. The content of a free polyvinyl alcohol in the aqueous emulsion is 0.2 to 20 parts by mass relative to 100 parts by mass of the ethylenically unsaturated monomer unit-containing polymer. The free polyvinyl alcohol has a degree of saponification of 80.0 to 99.5 mol % and a viscosity-average degree of polymerization of 200 to 5000, and the free polyvinyl alcohol has a symmetry factor (W.sub.0.05h/2f) that satisfies the following expression (1) as determined by gradient high-performance liquid chromatography for reversed-phase separation using a water-acetone eluent according to JIS K 0124 (2011).

The present invention relates to processes for the manufacture of aqueous polyurethane/acrylic hybrid dispersions that can be used as adhesives or coatings, are solvent free and have low VOC emissions, and are environmentally friendly. Also encompassed are the dispersions as such, compositions containing them and their use as coatings and adhesives.

Described are aqueous adhesive dispersions comprising dispersed polyurethanes and also ethoxylated fatty alcohols as emulsifiers. The polyurethanes are constructed from certain organic diisocyanates, dihydroxy compounds selected from certain polyester diols and polyether diols, and compounds having groups reactive toward isocyanate groups and having at least one ionic group. The adhesive dispersions can be used as laminating adhesives, for example for composite film lamination or for the lamination of rigid moldings with flexible decorative foils.
