In 2000, Nishida et al synthesized the PPDO whose molecular weight could reach 142,000 but the monomer conversion could only reach 79.4% by using stannous octoate as catalyst with co-initiator under conditions that T = 100oC, M/I = 4900, t = 20 h, in 2000, the enzymatic polymerization of PDO was carried out at 100oC for 15 hours using 5wt% immobilized lipase CA by Nishida et al.

这主要是因为PDO的结构相对稳定，开环聚合要比GA、LA、CL困难一些，而且用于PDO开环聚合的催化剂体系单一，主要集中在Ti， Zr， Sn， Ld， La， Yb， Hg等重金属，然而这些重金属作为副产物，不容易从PPDO中分离出来，阻碍了PPDO作为医用材料的应用，这也造成了PPDO的成本昂贵。
