Synthesis and Characterization of α, ω-Bis (3-Hydroxypropyl)-Functionalized Polysiloxane

摘要

Bis(3-hydroxypropyl)-functionalized polysiloxanes with various molecular weights were prepared using allyl alcohol and tetramethyldisiloxane as the first materials. At each step, the resulting compounds were characterized through FT-IR and NMR spectra, the results showed that each step was successfully carried out and objective products were prepared. The molecular weight of the polysiloxanes with varying dimethylsiloxane length were estimated by hydroxyl group analysis, ~1H NMR and GPC, which showed a good agreement between the theoretical molecular weight and those from these tests.
