Molecular crosslinks in polymers are added to increase mechanical strength and chemical resistances. Polymers, such as polyolefins, are difficult to install crosslinks as they have low functionality. Current Industry practice uses high energy hydrogen abstraction radical processes that have limited control. I will be presenting on a recent exciting development of a crosslinker capable of crosslinking any polymer containing any aliphatic C-H functionality. We will then investigate the addition of Dynamic functional groups to this “Universal Crosslinker” in the hopes to develop a drop in Covalent Adaptable Network (CAN) crosslinker. CANs are a class of crosslinked polymers that include dynamic covalent chemistry in the linkages. This allows for thermoset properties in working conditions, and thermoplastic properties (flow) under an applied stimulus.
