但聚二氧六环酮的结晶度较高，不适合直接用做药物控释材料，需要与其他单体进行共聚以改善其亲水性和结晶性等性质。
Poly(p-dioxanone) has high degree of crystallinity which limited it to copolymerize with other monomers to be used as controlled drug release materials.
研究单体不同分子量的变化对接枝反应和接枝样品亲水性等的影响。
The effect of molecular weight of monomer on grafting reaction and the hydrophilicity of grafting sample have been discussed.
亲水性聚合母体具有至少一单体，单体具有至少一第一官能基。
The hydrophilic polymer matrix is provided with at least one monomer; and the monomer is provided with at least one first functional group.
