双功能单体1-丙烯基缩水甘油醚是由烯丙基缩水甘油醚通过钌催化异构化反应以高产率制备的。 1-丙烯基缩水甘油醚进行容易的光诱导阳离子聚合，产生交联聚合物。使用 H-1- 和 C-13-NMR 光谱并采用充分表征的相关聚合物作为模型研究了该聚合物的结构。该模型聚合物是通过烯丙基缩水甘油醚与 BF3OEt2 的阳离子聚合，然后通过钌催化剂使烯丙基侧基异构化来制备的。随后，将所得的带有1-丙烯基醚侧基的聚醚进行二芳基碘鎓盐光引发聚合。聚合物光谱的比较表明聚合物主链中存在环状缩醛单元。 (C) 1994 约翰威利父子公司
The ambifunctional monomer, 1-propenyl glycidyl ether, was prepared from allyl glycidyl ether, by a ruthenium-catalyzed isomerization reaction in high yield. 1-Propenyl glycidyl ether undergoes facile photoinduced cationic polymerization to yield a crosslinked polymer. The structure of this polymer was studied using H-1- and, C-13-NMR spectroscopies and employing well-characterized related polymers as models. The model polymers were prepared by the cationic polymerization of allyl glycidyl ether with BF3OEt2 followed by isomerization of the pendant allyl groups by a ruthenium catalyst. Subsequently, the resulting polyether-bearing pendant 1-propenyl ether groups was subjected to a diaryliodonium salt-photoinitiated polymerization. A comparison of the spectra of the polymers indicated the presence of cyclic acetal units in the polymer backbone. (C) 1994 John Wiley & Sons, Inc.
