以 30 %的过氧化氢为引发剂,以混合过渡金属离子 (M²⁺)为主催化剂,合成了分子量在 650～ 850之间的水解聚马来酸,并进行了工业扩大生产,取得了预期的效果,工业生产的水解聚马来酸达到或超过了一等品的国家标准。该方法所用的催化剂和引发剂易得,用量少,价格低。工业扩大生产出的产品平均相对分子量分布范围窄,具有较好的阻垢作用。

Hydrolyzed polymaleic acid wassynthesized by catalysts of mixed transition metal ion, and initiated by hydrogen peroxide. The catalysts and the initiator in this method are easy to access, lower consumption, and lower cost. The industrial products have the better antiscaling ability.
