摘要
制备了不同铁含量、不同序列长度及分布的聚(苯乙烯──丙烯酸)铁配合物(SAAC·Fe)。考察了铁含量,序列长度分布和催化活性之间的关系,发现在Fe/COOH摩尔比为0.20时催化活性最高;当ASS+SSA=0.330,SSS=0.341,SAS=0.241时,SAAC·Fe显示最高的活性。
Poly (styrene acrylic acid)iron (SAAC. Fe) with various Fo contents and ditlcrentseguence distribution has been prepared. The infrared spectrum of SAAC. Fo indicatedthat the COO- group of SAAC tended to form bidentate bond with Fe. Therelationship among content of Fo and sequence distribution and catalytic activity wasexamined. It was foUnd that SAAC. Fo showed the highest activity at molar ratio 0.2of Fe/COO-, The highest activity of SAAC. Fe was also observed at ns of 3.0, nA, of1.0, (ASS +SSA) of 0.330, SSS of 0.341 and SAS of 0.241.
