Abstract

Polyurethanes (PUs) are big business. Their worldwide market tops 50 billion US$. They appear in paints, the soles of our shoes, car seats and even in tyres. Despite their huge market, current strategies in PU fabrication rely primarily on one approach. Two reactive monomers are combined; one comprising two nucleophilic groups (red puzzle piece) and the other two electrophilic groups (grey puzzle piece). Unfortunately, the requirement of this strategy for specialized monomers that must feature two reactive groups limits the potential of current PUs and adds expense to the fabrication process.

In our labs, we aim to provide access to more varied polyurethane-based materials. Materials that may be used to endow products with improved properties. To achieve this, we have developed catalytic strategies towards PUs that employ ambiphilic comonomers. These are monomers such as epoxides (blue puzzle piece) and isocyanates (white puzzle piece) that can function as both a nucleophile and an electrophile. The ready availability of these amphiphilic comonomers allows fast access to a wide variety of polymeric materials. This talk will tell the story of one catalyst we identified to be highly efficient for PU production. In particular, focus will be given to the understanding-based approach to optimisation of copolymerisation and how that understanding has allowed us to push the chemistry and access synthetically very challenging relatives of PUs.

This seminar is hosted by Dr Gareth Cave.

All welcome.
