Abstract
A new type of solid superacid (SO42-/TiO2/Nd3+) was used for the ring- opening polymerization of chloromethylthiirane (CMT). TiO2 . H2O immer sed in a sulfuric acid solution containing Nd3+ ions and calcined at 6 00 degrees C gave the solid superacid for initiating the polymerizatio n of CMT. The effects of polymerization temperature and amount of the initiator on the CMT polymerization were studied. Poly(CMT) obtained h as higher molecular weight ((M) over bar(W) = 52000) than ever reporte d.
