Lastly, I investigated dramatic mechanical properties from acrylate-functionalized PCOE. Attaching COOEt groups to an analog for partially-dehydrogenated PE produced a highly extensile and tough polymer. Even at small levels (~1%) of functionalization, we saw strain-at-break values >1000%.

I also explore acid-containing polyolefin synthesized by thiol-ene click chemistry. We explore three different pendant lengths and find both the extent of functionalization and pendant size tune the mechanical properties. The storage modulus in the rubbery regime is well described by both parameters

The linear OH-PCOE crystallizes faster and to a greater degree than branched EVOH or S2OH-PCOE. This greater crystallinity suggests it might make a better vapor barrier to preserve food. The S2OH-PCOE with longer pendants exhibits a more polar surface, which makes it a better adhesive than OH-PCOE.

In the OH-functionalized polymers, we compare linear and branched EVOH and a polymer with the OH at the end of a long pendant. The picture here gives a schematic representation of their chain and pendant architecture.

I work as part of a large team working to convert waste polyolefins (the plurality of plastic we produce) into high value functional polymers. We accomplish this by dehydrogenation to make C=C bonds, then functionalize those unsaturations to attach pendants that impart valuable properties.

My PhD research is motivated by the distressingly linear lifecycle of plastics. Approx 91% of new plastic is made from fossil sources. When we look at the other end of the life cycle, disposal, the situation is just as dire; we recycle < 9% of the plastic we throw away. Data from Plastics Europe

Found the database. This doesn't really scare me too bad, but I guess I live in Philly so I'm more confident than I should be because I'm seeing lots of Harris enthusiasm.
