Abstract
Organotin monomers containing dibutyltin groups - dibutyltin citraconate (DBTC) as a new monomer and dibutyltin maleate (DBTM) - were synthesized. Free radical copolymerizations of the organotin monomers with styrene (ST) and butyl acrylate (BA) were performed. The overall conversion was kept low (<= 15% wt/wt) for all studied samples and the copolymers composition was determined from tin analysis using the Gillman and Rosenberg method. The reactivity ratios were calculated from the copolymer composition using the Fineman-Ross (FR) method. The synthesized monomers were characterized by elemental analysis, H-1-, C-13-NMR and FTIR spectroscopy.
