Abstract
In this study, soluble double-chain (ladder-like) polysiloxane (DC-PS) was successfully prepared by intramolecular polycondensation (template polymerization) of polysiloxane, in which diethoxysilyl groups were introduced into the side chains, using hydrochloric acid and purified water as the catalysts. Based on the solubility, gel permeation chromatography, IR, 1H NMR, 29Si NMR, and transmission electron microscopy (TEM) results, it was found that DC-PS has a structure in which two polysiloxane chains are connected in parallel by urea bonds, although it is slightly defective, as the cyclic trimer component and the silanol group are present. In addition, thermogravimetric analysis (TGA) confirmed that DC-PS showed high thermal stability. Furthermore, a DC-PS cast film had relatively high water repellency, adhesion to a glass substrate, and surface hardness.
