Ester interchange reactions catalyzed by tin compounds in reactive processing: NMR contribution via reactions with model compounds

Marie-France Llauro, +1 more
- 01 Nov 2006 - 
TL;DR: In this article, Llauro et al. showed that the true catalytic entity is a dimeric alkoxy, acyloxy distannoxane entity formed in situ, during processing, by the reaction of the DBTO with the polymer ester groups.
