摘要： A moisture-curing hot-melt-adhesive composition in granulate, tablet or powder form can be produced by a.) fusing the reactive hot-melt-adhesive composition and heating the melt, subject to exclusion of moisture, b.) extruding this melt through one or more dies onto a cooled surface, subject to exclusion of moisture, c.) cooling the granulate, subject to exclusion of moisture, whereby the composition solidifies, d.) removing the cooled hot-melt-adhesive granulate, e.) filling the granulate into moisture-tight packages, subject to exclusion of moisture. These reactive hot-melt adhesives are pourable and free-flowing and therefore can be used with all conventional application machines for hot-melt adhesives.

摘要： Hotmelt polyurethane adhesive compositions which are solid at room temperature and capable of being cured by moisture are obtained by combining the reaction product of a polyisocyanate and a low molecular weight polymer derived from ethylenically unsaturated monomers and containing active hydrogen groups such as hydroxyl with an isocyanate-containing polyurethane prepolymer derived from one or more polyols. The low molecular weight polymer component may, for example, be obtained by free radical polymerization of mixtures of unsaturated monocarboxylic acids, alkyl esters of unsaturated monocarboxylic acids, and/or hydroxyalkyl esters of unsaturated monocarboxylic acids.

摘要： Reactive hotmelt adhesives based on liquid polyether polyols and/or polyester polyols and aromatic diols with at least one diisocyanate have a very low melt viscosity and high early strength. They are particularly suitable for the bonding of substrates of poor thermal conductivity, such as foams and nonwoven materials, and heat-sensitive substrates.

摘要： Polyurethane compositions are produced in a two-stage method. In a first step, a diol component with a molecular weight of less than 2000 is reacted with a monomeric diisocyanate with a molecular weight of less than 500 and the unreacted monomeric diisocyanate is removed from this reaction product. In a second step, the resulting high-molecular diisocyanate is reacted with a polyol to produce a reactive prepolymer with isocyanate and groups. The addition of polyisocyanates which are capable of migration and which have a substantially lower vapor pressure than diphenylmethanediisocyanate, improves the addition behavior of the invention polyurethane compositions. Reactive polyurethane compositions of this type are suitable for using as binding agents for reactive one or two component adhesives/sealants, which may optionally contain solvents. These compositions are also suitable for producing reactive hot melt adhesives when suitable polyols are selected. A substantial advantage of these compositions compared to known polyurethane compositions is the considerably lower proportion of monomeric diisocyanates with a molecular weight of less than 500.
摘要翻译：聚氨酯组合物以两段法制备。在第一步中，分子量小于2000的二醇组分与分子量小于500的单体二异氰酸酯反应，并从该反应产物中除去未反应的单体二异氰酸酯。在第二步中，所得的高分子二异氰酸酯与多元醇反应以产生具有异氰酸酯和基团的反应性预聚物。能够迁移并且具有比二苯基甲烷二异氰酸酯基本上更低的蒸气压的多异氰酸酯的添加改善了本发明聚氨酯组合物的添加行为。这种类型的反应性聚氨酯组合物适合用作反应性一种或两种组分粘合剂/密封剂的粘合剂，其可以任选地含有溶剂。当选择合适的多元醇时，这些组合物也适用于制备反应性热熔粘合剂。与已知的聚氨酯组合物相比，这些组合物的显着优点是分子量小于500的单体二异氰酸酯的比例相当低。
