定量地求得丁-戊共聚物二元组分布及数均序列长度数据。
The dyad distribution and number-average sequence length of these copolymers were quantitatively determined.
同时，共聚物中亲水组分—NVP的引入，对酸性条件下的释放影响不大，但明显加快了药物在碱性条件下释放。
While NVP was incorporated into polymer drug, it had little effect on release in acid condition, but drug release rate in base condition increased markedly.
所述 组合物包含至少一种是包括由丙烯衍生的单元的聚合物的组分，和至少 一种是苯乙烯类嵌段共聚物的组分。
The compositions incorporate at least one component that is a polymer including propylene-derived units and at least one component that is a styrenic block copolymer.
通过改变组分及共聚物合成工艺，可以调整其降解周期和亲水性能。
The copolymers' degeneration speeds and hydrophilic properties can be adjusted by changing the raw material's formulae and copolymerization conditions.
