The present invention relates to compositions comprising poly-HEMA having a peak molecular weight between about 25,000 and about 100,000, preferably between 25,000 and 80,000 and a polydispersity of less than about 2 to less than about 3.8 respectively and covalently bonded thereon, at least one cross-linkable functional group. The present invention further relates to low polydispersity poly-HEMA suitable for making the crosslinkable prepolymers, processes for functionalizing and purifying said poly-HEMA to form said crosslinkable prepolymers, viscous solutions made from said crosslinkable prepolymers, hydrogels made from said viscous solutions and articles made from said crosslinkable polymers, hydrogels and viscous solutions.
本发明涉及一种含有聚HEMA的组合物,其峰值分子量在大约25,000至大约100,000之间,优选在25,000至80,000之间,并具有聚分散度分别小于约2至小于约3.8的至少一个可交联官能团共价键结合在上面。本发明还涉及适用于制备可交联预聚物的低聚分散度聚HEMA,将所述聚HEMA功能化和纯化以形成所述可交联预聚物的过程,由所述可交联预聚物制成的粘稠溶液,由所述粘稠溶液制成的水凝胶以及由所述可交联聚合物、水凝胶和粘稠溶液制成的物品。
