A bit late post but happy I could attend #MACRO2024 this year. It was a bit hectic but totally worth it, great to catch up with friends old and new :) Now back to maternity break, see you soon! @mothersinsci

[Magdalena Beres 🇺🇦 @MagdaBeres]

@fred_opj Thanks Fred! Yes, this is really interesting, I have even carried out photoRAFT with light wavelengths which had no overlap with the abs spectrum

[Magdalena Beres 🇺🇦 @MagdaBeres]

Interested in RAFT? Polymerization kinetics? Photopolymerizations? Look now further and check out our work on the effect of monomer, RAFT agent and light intensity on the kinetics of photoiniferter-RAFT polymerization

[Team Perrier @TeamPerrier]

We have just published an excellent paper on Kinetic investigation of photoiniferter-RAFT polymerization in continuous flow using inline NMR analysis.

@AmyGodfrey23 @LabGibson @MRCDTP_IBR @markvanraaij @craigpthomp Congrats! :)

[Magdalena Beres 🇺🇦 @MagdaBeres]

Bitter-sweet feelings as my time at Monash is over. I had a great time exploring flow chemistry and Australia. Huge thank you to everyone in the PRD group,you made me feel very welcome. Thanks to Tanja Junkers and @SebPerrier for this opportunity! @TeamPerrier

[Magdalena Beres 🇺🇦 @MagdaBeres]

@AnastasakiLab @MariaNefeli12 Well done @MariaNefeli12, congratulations!

@ItsJamesWilson @pratik_gurnani The old ones we have at Warwick are from Mylee brand but I'm not sure if their design hasn't changed over time

[Magdalena Beres 🇺🇦 @MagdaBeres]

@ItsJamesWilson You could try using UV lamp used for visualisation of TLCs

[Magdalena Beres 🇺🇦 @MagdaBeres]

@ChemistMhmdJ To improve the second factor (stability of TTC end group) - there are some reports showing that adding a tertiary amine can reduce TTC radical to a TTC anion which prevents degradation. However, we haven’t seen big improvements in our system.

[Magdalena Beres 🇺🇦 @MagdaBeres]

What can we learn about photo-iniferter RAFT polymerization of methacrylates using bis-trithiocarbonate RAFT agents? #RSCPoster #RSCMat @TeamPerrier @Polymer_RTP @warwickchem

[Magdalena Beres 🇺🇦 @MagdaBeres]

@ChemistMhmdJ Green light works better than blue so likely shifting to even longer light wavelength could improve the livingness. However, this will increase time reaction significantly and can also lead to poor initiation, which will lead to broader dispersity.

[Magdalena Beres 🇺🇦 @MagdaBeres]

@ChemistMhmdJ It's a going bit of a long answer but there's quite a few factors to consider here ;)

[Magdalena Beres 🇺🇦 @MagdaBeres]

@Bellotti_Vale @AnastasakiLab How the photocatalyst will affect the recovery of monomer and RAFT agent? Can you remove the Eosin easily?

[Magdalena Beres 🇺🇦 @MagdaBeres]

@Satu_Hakkinen So in short, I think majority of CTA participates in initiation but I haven't than quantitative studies /3

[Magdalena Beres 🇺🇦 @MagdaBeres]

@Satu_Hakkinen For MMA I suspect it's similar as I don't have (big) initialisation period. I think for PMMA the main problem is the end group degradation which will happen throughout the entire polymerization and this would be applicable to every trithiocarbinate based RAFT agent! /2
