In producing Mn Si alloys with hot furnace, feedingratio of s? Mn is regulated, and slag amount and pH value are controled.

The effects of feedingratio, initiator type and concentration on the copolymerization were studied. The obtained copolymer was characterized by FTIR, 1H NMR and 13C NMR.
Under the condition of sodium chloride feedingratio 7.5%, molecular sieve and refined product feedingratio 1:1, the DOL product purity was up to 99.9% which had met the product quality requirements.
