Direct 'in situ', low VOC, high yielding, CO2 expanded phase catalytic chain transfer polymerisation: towards scale-up.

Dalton transactions (Cambridge, England : 2003)

Adlington K, Green A, Wang W, Howdle SM, Irvine DJ.
PMID: 23085824
Dalton Trans. 2013 Jan 07;42(1):127-36. doi: 10.1039/c2dt31822a.

The successful application of catalytic chain transfer polymerisation (CCTP) by adopting an 'in situ' catalyst preparation methodology in several polymerisation media is described. More specifically, this study is focused on reporting the development of 'in situ' CCTP within a...
