摘要: A new type of solid superacid (SO 4 2- /TiO 2 /Nd 3+ ) was used for the ring opening polymerization chloromethylthiirane (CMT). TiO .H O immersed in a sulfuric acid solution containing Nd ions and calcined at 600°C gave initiating CMT. The effects temperature amount initiator on CMT were studied. Poly(CMT) obtained has higher molecular weiight (M w = 52000) than ever reported
