“…However, during this process, problems of the depletion of petroleum resources, environmental pollution, and waste disposal have become increasingly prominent. [4][5][6][7][8] Among them, polyols synthesized from ring opening reaction of epoxidized triglyceride oils in the presence of acid catalysts is one of the most exploited process. During all these researches, nature oils are supposed to be the ideal candidates and consequently attracted considerable attentions with regard to their relatively low cost, readily availability, renewable, biodegradable, and eco-friendly properties.…”

In this article, a series of sustainable polyurethanes are prepared by introducing different content of cyclic polysilanol, which may act as a chain extender to replace 1, 4-butanediol (BDO). Consequently, cyclic polysiloxanes are successfully incorporated into the molecular chains to afford organic-inorganic polyurethanes and then their effects on polyurethanes thermal properties and surface hydrophilicity are fully characterized by thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), and contact angle testing. Results show that the hybrid polyurethanes display enhanced glass transition temperatures (T g ). While in terms of TGA, the effects of cyclic polysilanol on thermal properties seem complex, which would reduce the thermal stability in the first degradation process but enhance in the second process. The morphology observed by scanning electron microscopy (SEM) show that the inorganic constitutions, namely, cyclic polysilanol, may occur to self-condensation or aggregation, which can help to explain the uncommon thermal phenomenon above. Thus, an opportunity of future applicability in the areas of sustainable polymer with improved properties can be envisioned in our research method of hybrid polyurethanes.

“…Volumetric shrinkage was measured by comparison of density before and after cure. The shrinkage of VE-6001 UV was about 0.6 %, which was lower than commercially available acrylic OCRs (about 3~4 %) [6]. Low shrinkage minimizes stress from shrinkage during cure, an advantage for both large and small area displays.…”
