以2-甲基-2-恶唑啉为起始原料，经3-氨丙基三乙氧基硅烷封端，成功地合成了端硅基聚恶唑啉。采用双官能度引发剂合成了三乙氧基硅基封端的聚恶唑啉。此外，具有两个或三个三乙氧基甲硅烷基的聚恶唑啉通过使用二烯丙基胺作为终止剂，然后与三乙氧基硅烷进行硅氢化反应来制备。采用溶胶-凝胶法，将这些三乙氧基硅烷封端的聚恶唑啉与正硅酸乙酯进行酸催化共水解聚合，制备了一种新型的有机-无机聚合物杂化材料，该杂化材料为均匀透明的玻璃态复合材料
Polyoxazoline having a terminal triethoxysilyl group was successfully synthesized openingpolymerization of 2-methyl-2-oxazoline followed by termination with (3-aminopropyl)triethoxysilane. Triethoxysilyl-terminated telechetic polyoxazoline was prepared by using a bifunctional initiator. Furthermore, polyoxazolines having two or three triethoxysilyl groups were prepared by using diallylamine as a terminator followed by a hydrosilation reaction with triethoxysilane. These triethoxysilyl-terminated polyoxazolines were subjected to acid-catalyzed cohydrolysis polymerization with tetraethoxysilane by the so-called sol-gel method to produce a novel organic-inorganic polymer hybrid, which was a homogeneous transparent glassy composite material
