中文名稱：聚己内酯-b-聚乙二醇-b-聚己内酯(x/y/x)

英文名稱：PCL-b-PEG-b-PCL

分子式：H(OCH2CH2CH2CH2CH2CO)mO(CH2CH2O)n(COCH2CH2CH2CH2CH2O)mH

生物相容性、兩(liǎng)親性三嵌段聚合物，由親水性、中心PEG嵌段和兩(liǎng)個末端疏水性PCL嵌段組成(chéng)。這(zhè)些材料已用于藥物輸送應用以及熱塑性彈性體。通過(guò)控制每個聚合物塊的相對(duì)長(cháng)度，可以制備具有不同性質的定義明确的材料。羟基端接允許對(duì)這(zhè)些材料進(jìn)行簡單的進(jìn)一步化學(xué)改性。

Biocompatible, amphiphilic triblock polymer composed of a hydrophilic, central PEG block and two terminal hydrophobic PCL blocks. These materials have been used in drug delivery applications as well as thermoplastic elastomers. Well-defined materials with varying properties can be prepared by controlling the relative length of each polymer block. Hydroxyl termination allows for facile further chemical modification of these materials.
