The process includes the steps of reacting a plurality of ethylenically unsaturated monomers and a reaction moderator with a macromer having induced unsaturation in the presence of a carrier polyol, a free radical polymerization initiator, and a first graft polyol.

本发明方法包括使多种烯键不饱和单体和反应调节剂与具有诱导不饱和度的大分子单体在载体多元醇、自由基聚合引发剂和初级接枝多元醇存在下反应的步骤。

The main reasons are: the reaction+=Fe+CO also occur during molten iron drop passing final slag, the slag has lowlevel of FeO ,but it still has strong decarburizing capability. In addition, during molten irondrop passing final slag, the dynamic conditions of decarburizing reaction is well, it makethe carbon content of liquid iron reduce.

主要是因为铁滴穿过终渣时也发生+=Fe+CO 反应，此时渣中含量虽少，脱碳反应的动力学条件很好，具有较强的脱碳能力。
