Polyphosphate is another new biodegradable material with a rapid development.

聚磷酸酯是近十几年来发展较快的另一类新型生物可降解材料。

As for the reaction of polyphosphate and hydroxyl compound,because of the reaction activity,high polyphosphate of long line is broken down to low polyphosphate,and finally the product consist of phosphoric acid,monoester phosphate,diester phosphate and pyrophosphate.

计算结果表明,多聚磷酸与羟基化合物反应时,由于高聚磷酸的反应活性比低聚磷酸高,反应时直链的高聚磷酸逐步从中间链段断裂,生成低聚磷酸化合物,最终产物是磷酸、磷酸单酯、磷酸双酯、焦磷酸及其酯的混合物。
