摘要

<正> Styrene-acrylic acid copolymer （SAAC）-supported iron complex （SAAC·Fe）was characterized and the effect of the characteristic parameters on the catalytic activity of the complex was investigated. IR spectrum suggested that the complex SAAC·Fe possesses a structure of（C）and the Fe-O bond is higher in covalency.The complex SAAC·Fe with the structure of（C）shoved a higher catalytic activity in butadiene polymerization. When Fe/-COOH molar ratio in SAAC·Fe was about 0.2 the complex gave optimum catalytic activity. The catalytic activity of SAAC·Fe with the higher content of long sequence of acrylic acid units was low. When the content of the short sequence of acrylic acid units was predominant and at the same time the content of the short sequence was approximately equal to that of the long sequence for stryrene

the activity of the complex was high.
