摘要
PS/MWNT composites have been prepared by supension polymerization.It was obvious that the yield of PS was lower for the addition of MWNT.GPC tests showed when the added amount of MWNT was smaller,the molecular weight of PS was higher than that of pure PS for the volume effect of MWNT terminating PS chains.And when the added amount of MWNT was larger,the molecular weight of PS was lower than that of pure PS for the weaker activity of free radicals and interference of MWNT.
