New paper on phostones and poly(phosphonate)s!

Great work by Emily with the Wurm group at the Max Planck Institute for Polymer Research. This paper describes the synthesis of phostones, i.e., 2-alkoxy-2-oxo-1,3-oxaphospholanes, and their use in the preparation of linear poly(phosphonate)s via ring-opening polymerization resulting in polymers with a hydrolytically stable P–C bond in the polymer backbone. Phostones have the stable P–C bond within the cycle, which leads to a dramatic increase of the monomer stability toward hydrolysis and long shelf-lives compared to other cyclic phosphoesters, which hydrolyze immediately at contact with water.

Fern’s new cross-metathesis paper!

Cross-metathesis functionalised exo-olefin derivatives of lactide
Fern’s latest work explores the use of two derivatives of lactide, each of which features an exocyclic olefin, and their pre-polymerization modification by olefin cross-metathesis. The ring-opening polymerization of these new monomers, and their hydrogenated congeners, is facilitated by organo- and Lewis-acid catalysts. Together, they offer a new strategy for derivatizing and altering the properties of poly(lactic acid).

Sayonara Mike!

We’ve recently bid a fond farewell to Mike as he spends the next two months as a visiting professor at Nagoya University in Japan!

The University of Edinburgh and the Graduate School of Sciences at Nagoya University have strong links through a joint degree program so hopefully this will be the start of some fruitful collaborations. We recently had some researchers from Nagoya visit Edinburgh for a joint symposium in November: Prof. Yuko Okamoto (Biophysics), Dr. Keiichiro Imura (Solid-state Physics), Dr. Yusuke Nakanishi (Physical Chemistry), Prof. Kunio Awaga (Solid-state chemistry). Hopefully Mike will have similar success in getting everyone excited about polymers!

Feel free to contact Mike while he’s away (he’s only 9 hours ahead of GMT) and he’ll get back to you as soon as possible.

As he’s away for December and January we moved our Festive Dinner forward to November. Everyone was having too much fun to remember we still need a new group photo, but thankfully Yuechao got a picture of Mike enjoying himself:

Congratulations Dan!

A big well done to Dan (and Ben) for his work on the organometallic-mediated radical polymerization (OMRP) of methyl methacrylate (MMA), styrene, and vinyl acetate, mediated by a novel tert-butyl-substituted amine–bis(phenolate) iron(II) complex in the absence of a halide source for an organometallic-only route to controlled radical polymerization. Check it out below:
