以3-羟基丙酸(3-HP)为单体,金属铪(Ⅳ)催化合成了高纯度的聚3-羟基丙酸[P(3-HP)]。3-HP和P-(3-HP)的结构经NMR,FT-IR和GPC等表征。
High pure poly(3-hydroxypropionic acid) [ P(3-HP) ] was synthesized from 3-hydroxypro- pionic acid(3-HP) by direct catalyzed condensation using metal Hafnium ( IV ) as a catalyst. Their structures were characterized by NMR, FT-IR and GPC.
