Abstract
The interfacial polymerization technique has been used in the preparation of poly(organotin phosphonates). Dialkyltin dichloride, tetraalkyldichlorodistannoxane or hexaalkyldichlorotristannoxane dissolved in an organic solvent immiscible with water was brought into reaction with the disodium salt of phenylphosphonic acid to give the corresponding poly(organotin phosphonate). The solubility of the polymers in organic solvents decreased with increasing tin content.
