    摘要: Polyolefine-based mouldings and foils contain internal bonding additives which are enriched by migration at the plastic surface and which have their molecular structure bonding substituents of higher polarity on an oleophilic hydrocarbon radical. At least one part of these internal additives is hardened via its hydrocarbon radicals in the area of the plastic surface and prevented from further migrating, and so permanent adhesive bondings and/or coatings of the polyolefine surface may be obtained without additional preliminary treatments. Also disclosed is a process for furnishing solid polyolefine surfaces with such adherence-improving, immobilised additive (mixtures), and other auxiliary agents used for that purpose.

    摘要: The bondability of a polyolefin, particularly to cyanoacrylate adhesives, is improved by incorporating in the polyolefin a polymerization initiator capable of initiating the polymerization of the monomers constituting the cyanoacrylate adhesive. The polymerization initiator may, for example, be a sterically hindered nitrogen base and may be mixed with the polyolefin at a temperature above the polyolefin's glass transition temperature using, for example, co-extrusion or co-injection methods.

    摘要: A composition of matter comprising a resin obtained by a process comprising reacting at an elevated temperature an epoxidized ester of an unsaturated fatty acid with an aliphatic alcohol with a resin acid is provided. The equivalent ratio of epoxy groups of said epoxidized ester to carboxyl groups of said resin acid is in the range from 1.5:1 to 0.01:1. The resin is useful as a tackifier for adhesives and has a reduced tendency to crystallize.
