Résumé : |
The use of a tertiary isocyanate monomer simplifies the preparation of solvent-free dispersions because heat can be used instead of solvents to reduce the viscosity during the dispersion step. Adhesives prepared from m-TMXDI tertiary isocyanates provide a lower heat activation temperature relative to other aliphatic isocyanates, and their activation temperature remains stable for at least six months. The lack of side reactions also allows the controlled incorporation of structure modifiers into the backbone polymer of the dispersion. Preliminary work suggests this may provide a technical approach to increase the range between the activation temperature and the heat resistance temperature as adhesives without the use of external crosslinking agents. |
