Polymers with Tin as a Pendant Group

Copolymerization with methyl methacrylate was also performed and produced random copolymers. The introduction of the MesSn group into the poly(methylmethacrylate) depressed the Tg by 75 °C cf. poly(methylmethacrylate) (PMMA). 

A number of organotin polyesters, polyamides, polythiols, polyethers, and polyaminoesters have been synthesized from dialkyltin halides with dicarboxylic acids, diols, diamines, dithiols, urea, thiourea, amino acids, and hydroxyl acids involving polycondensation reactions. These polymers have potential applications as thermostabilizers for PVC.
