Abstract
A mixture may include at least one polymerizable species and at least one thermoresponsive supramolecular initiator complex involving a host-guest interaction. Processes for making resins may include mixing at least one polymerizable species with at least one thermoresponsive supramolecular initiator complex involving a host-guest interaction; subjecting the mixture to a temperature above about 30° C. thereby promoting the dissociation of the at least one thermoresponsive supramolecular initiator; and allowing the mixture to cure at the temperature for a period of time.
Claims25
A mixture, comprising:
- at least one polymerizable species;
- and
- at least one thermoresponsive supramolecular initiator complex involving a cyclic or polycyclic polyether and a hydrogen bond donor reactive species linked by a host-guest interaction, and
- wherein disrupting the host-guest interaction initiates the polymerization of the at least one polymerizable species.
A process for making a resin, comprising:
- mixing at least one polymerizable species with at least one thermoresponsive supramolecular initiator complex involving a cyclic or polycyclic polyether and a hydrogen bond donor reactive species linked by a host-guest interaction, and
- wherein disrupting the host-guest interaction initiates the polymerization of the at least one polymerizable species;
- subjecting the mixture to a temperature above about 30° C., thereby promoting the dissociation of the at least one thermoresponsive supramolecular initiator;
- and
- allowing the mixture to cure at the temperature for a period of time.
