新型羟烷基氨基甲酸酯，二羟烷基氨基甲酸酯封端的聚（二甲基硅氧烷）（PDMS）低聚物，和氨基甲酸酯连接的嵌段共聚物与聚（ε-己内酯）（PCL）的设计，合成，并使用组合和高通量实验（CHTE）的特点。通过使3-氨丙基封端的PDMS低聚物与碳酸亚乙酯（EC）反应，合成了新型羟烷基氨基甲酸酯封端的PDMS低聚物;这些低聚物与e-己内酯（e-CL）进一步反应，得到新型氨基甲酸酯连接的PCL-PDMS-PCL三嵌段共聚物。通过使3-氨丙基封端的PDMS与碳酸甘油酯（GC）反应，合成了新型的二羟基烷基氨基甲酸酯封端的PDMS低聚物;这些低聚物与e-CL进一步反应，得到新型的PDMS和PCL的H型嵌段共聚物。合成的低聚物和嵌段共聚物的结构表征进行了高通量FTIR，DSC和NMR。低聚物和嵌段共聚物的分子量分别为10000和10000。
Novel hydroxyalkyl carbamate, dihydroxyalkyl carbamate terminated poly(dimethylsiloxane) (PDMS) oligomers, and carbamate-linked block copolymers with poly(e-caprolactone) (PCL) were designed, synthesized, and characterized using combinatorial and high-throughput experimentation (CHTE). Novel hydroxyalkyl carbamate terminated PDMS oligomers were synthesized by reacting 3-aminopropyl terminated PDMS oligomers with ethylene carbonate (EC); further reaction of these oligomers with e-caprolactone (e-CL) resulted in novel carbamate-linked PCL−PDMS−PCL triblock copolymers. Novel dihydroxyalkyl carbamate terminated PDMS oligomers were synthesized by reacting 3-aminopropyl terminated PDMS with glycerine carbonate (GC); further reaction of these oligomers with e-CL resulted in novel H-type block copolymers of PDMS and PCL. Structural characterization of the synthesized oligomers and block copolymers was carried out with high-throughput FTIR, DSC, and NMR. Molecular weights of the oligomers and block copolymers were...
