摘要
本文研究了马来酸酐（MAn）在过氧化苯甲酰（BP）引发作用下与醋酸乙烯酯（VAc）的交替共聚反应。红外光谱证明了交替共聚物的结构，分析结果表明共聚物是由反应单体技1：1摩尔比例组成。当c（BPO）＝6．8×10^（－3）moi／L，c（VAc）＝3．4×10^（－3）mol／L，p（MAn）＝32．7g／L，63～65℃反应18小时，转化率可达92％以上。
Benzoyl peroxide appeared an effective initiation system for the alternatingcopolymerization of Vinyl acetate onto Maleic anhydride infrared spectral analysis has beenadoated to prove the structure of the reaction product' Analyical result showed thatconsitituent of copolymerization was VAc/MAn=1: 1 (molar ratio). When the reaction wascarried out at 63-65℃ for 18 hours, c (BPO )＝6. 8×10-3mol/L, c(VAc)＝3.4×10-3'mol/L'p (MAn)＝32. 7g/L, The yield was aboue 92%
