Procedure

The monomers of P51 were first synthesized. Tri-n-butyltin methacrylate was prepared as was tripropyltin methacrylate. These esters were isolated as crystals from petroleum ether. Methyl methacrylate was uninhibited. All uninhibited monomers were refrigerated below 40° F when stored for short periods of time. Tri-n-butyltin methacrylate (0.4 mole), tri-n-propyltin methacrylate (0.4 mole) and methyl methacrylate (0.4 mole) were reacted in 300 ml of benzene using benzoyl peroxide (0.5% by weight) as initiator. The reaction mixture was refluxed for 24 hours in a 1-liter, 3-necked resin flask equipped with a reflux condenser, a thermometer, such that it read the temperature of the reactants and a mechanical stirrer. The resultant polymer was clear and could be cast as a film from the benzene solution. Analysis showed 29.35% Sn.
