Hot-melt adhesive compositions comprising acidic polymer and basic polymer blends |
摘要 |
A hot-melt adhesive composition comprises a blend of at least one acidic polymer and at least one basic polymer. At least one of the polymers is a hot-melt adhesive. Thermally reversible crosslinks are formed between each of the two polymers. These crosslinks impart cohesive strength to the applied adhesive, without sacrificing ease of processing.
