Long-range order in organotin monomers and polymers

Kristina Zubow, Anatolij Zubow, Viktor Anatolievich Zubow


Using gravitationalmass spectroscopy (GMS) the long-range order (LRO) in organotinmonomers and polymers (OTP) in the solid (film) and solved (highly dissolved in p-xylene) state was investigated. The GMS spectra of OTP, maleic anhydride (MA) – styrene (St) copolymer, etherified with bis(tri-n-butyltin)oxide, in solution (with subtracting the solvent signals) and in film were given further, those of the copolymers St-bis(tri-nbutyltin) maleinate and St-bis(tri-n-butyltin)fumarate and of the monomers bis(tri-n-butyltin)maleinate and bis(tri-n-butyltin)fumarate. The cluster of (+SnBu3)6 and its associates was modeled. OTP were concluded to be thermodynamically unstable solid nanoemulsions of the first order of (+SnBu3)6 clusters in the polymermatrix. The mechanismof the hydrolytic cleavage of OTP was discussed. It was analyzed how temperature influences LRO in the phenol formaldehyde OTP and how the thermal cross linking proceeds.
