【摘要】 以外式-N-乙酰氧基-7-氧代双环[2.2.1]庚-5-烯-2,3-二羧酰胺(AOHD)或外式-N-苯磺酰氧基-7-氧代双环[2.2.1]庚-5-烯-2,3-二羧酰胺(POHD)为单体,以Grubbs络合物RuCl2(PCy3)2(=CH-Ph)为引发剂进行开环歧化聚合(ROMP),获得大分子引发剂PAOHD-Br(Mn:5.53×103,PDI:1.09)或PPOHD-Br(Mn:8.50×103,PDI:1.49)。再以甲基丙烯酸甲酯(MMA)为单体、以双甲基丙烯酸乙二醇二酯(EGDMA)为交联剂,在大分子引发剂PAOHD-Br或PPOHD-Br作用下,通过电子转移使活化剂再生的原子转移自由基聚合(ARGET ATRP)成功地制备出数均分子量为(4.92-5.03)×105的微凝胶负载的酰化试剂(MGARs)。更多还原

【Abstract】 A Ring Opening Metathesis Polymerization(ROMP) was conducted with exo-N-acetyl-7-oxabicyclohept-5-ene-2,3-dicarboximide(AOHD) or exo-N-phenylsulfonyl-7-oxabicyclohept-5-ene-2,3-dicarboximide(POHD) as a monomer and Grubbs complex RuCl2(PCy3)2(=CH-Ph) as an initiator,and a macroinitiator PAOHD-Br(Mn: 5.53×103,PDI: 1.09) or PPOHD-Br(Mn: 8.50×103,PDI: 1.49) was obtained.Under the function of the macroinitiator PAOHD-Br or PPOHD-Br,the microgel-supported acylating reagents(MGARs) [Mn:(4.92-5.03)×105] were successfully synthesized via Activator Regenerated by Electron Transfer for Atom Transfer Radical Polymerization(ARGET ATRP) with methyl methacrylate(MMA) as a monomer and ethyleneglycol dimethacrylate(EGDMA) as a cross-linker.更多还原
