还是这里人气旺 sacrificial initiator一般在ATRP文献中有出现 求教大虾们啦 无限感谢  |

A sacrificial initiator,ethyl 2-bromoisobutyrate(EBiB), was also added so that the molecular weight of the grafted polymer could be tailored. EBiB will also initiate polymerizaiton, causing a bulk polymer to form simultaneously to the graft-copolymer from the surface. 但好像sacrificial initiator一般在ATRP中提到是和initiator terminationi并存的 |

xgyanger说对了 我看的正是surface initiate ATRP法 但之前没去想过它的具体作用 你的理解可能是对的 再结合下上下文看看 A sacrificial initiator,ethyl 2-bromoisobutyrate(EBiB), was also added so that the molecular weight of the grafted polymer could be tailored. EBiB will also initiate polymerizaiton, causing a bulk polymer to form simultaneously to the graft-copolymer from the surface. Because the amount of sacrificial initiator is much larger than the amount of initiator attached to the surface, the amount of initiator attached to the surface is neglected, and the molecular weight of the resulting bulk and grafted polymer is only a function of the sacrificial initiator-to-monomer ratio. This is a common method to control the length of the grafts from surface confined initiators. 但不大理解倒数第二句only function指的内容 看来得找找文献看看 xgyanger是做ATRP的么 谢谢指教哈 |
