    摘要: A coextrudable adhesive composition formed from a polymer component and a catalytic agent is disclosed. The polymer component is selected from grafted polymers formed by grafting polyolefins with an ethylenically unsaturated carboxylic acid or anhydride. The catalytic agent is a monoalkyl phosphate, alkylamine, heterocyclic compound or aminocarboxylic acid. The compositions show improved adhesion to polar substrates compared with the related compositions that do not contain the catalytic agent. The compositions may be used, for example, in the bonding of ethylene/vinyl alcohol polymers to polyolefins and polyamides.

    摘要: A cross-linkable hot-melt adhesive is prepared by mixing an acid graft modified propylene/olefin copolymer with an epoxy cross-linking agent and a tertiary amine catalyst. The adhesive is cross-linked at an elevated temperature such as when melt mixing the components.
