Abstract: Insoluble diorganotin functionalized polymers of the type (P-H)(1-t)(P-(CH2)(n)SnBuX2)(t), with n = 4, 6, X = Ph, Cl, and t being the degree of functionalization, were synthesized from Amberlite XE-305, an insoluble polystyrene (P-H) cross-linked with divinylbenzene. The synthesis conditions used gave rise to functionalization degrees varying from 25% to 30%. The tin-functionalized polystyrenes were characterized by elemental analysis, IR, and Raman as well as solid-state Sn-117 and C-13 NMR spectroscopy. Methodological and chemical features related to the determination of the functionalization degree have been investigated in detail. The catalytic activity of the Amberlite-grafted tin functionalities in transesterification reactions was studied.
