    Abstract: 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.

    Abstract: A primer composition and method for improving adhesion of polymeric material to metal ion containing substrate is provided. The primer consists of a solution of a polymer whose chain contains polar groups, such as carboxy, hydroxy, groups and the like, and non-polar monoethylenically unsaturated terminal groups. The primer is applied to the surface to be treated, the solvent evaporated and the polymeric material applied and cured in the usual way. The bond tensile strength of samples employing the primer composition is substantially increased as compared to the bond tensile strength of samples not employing the primer composition of this invention.
