Polysilylether: A Degradable Polymer from Biorenewable Feedstocks

2016

The synthesis of polysilylethers (PSEs) using a monomer derived from a biorenewable feedstock is reported. The AB-type monomer was synthesized from undecenoic acid through hydrosilylation and reduction, and the polymerization was catalyzed by earth-abundant metal salts. High-molar-mass products were achieved, and the degree of polymerization was controlled by varying the amount of an AA-type monomer in the reaction. The PSEs possess good thermal stability and a low glass-transition temperature (Tg ≈-67 °C). To demonstrate the utility of the PSEs, polyurethanes were synthesized from low-molar-mass hydroxy-telechelic PSEs.

Three new polymerizable diols, based on mono‐, di‐, and tri‐O‐allyl‐L‐arabinitol derivatives, were prepared from L‐arabinitol as versatile materials for the preparation of tailor‐made polyurethanes with varied degrees of functionalization. Their allyl functional groups can take part in thiol‐ene reactions, to obtain greatly diverse materials. This “click” reaction with 2‐mercaptoethanol was firstly studied on the highly hindered sugar precursor 2,3,4‐tri‐O‐allyl‐1,5‐di‐O‐trityl‐L‐arabinitol, to apply it later to macromolecules. A polyurethane with multiple pendant allyl groups was synthesized by polyaddition reaction of 2,3,4‐tri‐O‐allyl‐L‐arabinitol with 1,6‐hexamethylene diisocyanate, and then functionalized by thiol‐ene reaction. The coupling reaction took place in every allyl group, as confirmed by standard techniques. The thermal stability of the novel polyurethanes was investigated by thermogravimetric analysis and differential scanning calorimetry (DSC). This strategy provides a simple and versatile platform for the design of new materials whose functionality can be easily modified. © 2010 Wiley Periodicals, Inc. J Polym Sci Part A: Polym Chem, 2011

“…Polymeric materials comprising of inorganic and metal elements have always been the focus of many researchers to harness the unique properties of such polymers. Poly(silyl ether)s, for instance, is a silicon containing polymer which epitomizes an important category of useful materials such as polymeric membranes [3] , conducting polymers [4] , plastics and elastomers [5][6][7] , stimulus-sensitive materials and so on [8] . Silicon containing polymers, commonly known as polysiloxanes, have received much scientific consideration as a functional and high-performance polymeric materials owing to their significant flexibility at low temperatures and enhanced stability at high temperatures.…”

Synthesis, characterization and antibacterial activity of novel poly(silyl ether)s based on palm and soy oils

et al. 2018

In this research, palm oil and soy oil were used as a natural polyol to prepare novel poly(silyl ether)s. Palm oil and soy oil were first converted to monoglyceride by one step via alcoholysis process in the presence of 0.1% CaO as a catalyst. The monoglycerides were characterized by Fourier transform infrared spectrometer (FT-IR), nuclear magnetic resonance (NMR) and iodine test. The novel poly(silyl ether)s were prepared via polycondensation reaction between dimethyldichlorosilane with monoglycerides based on palm and soy oils, respectively. FT-IR, NMR and silicone-29 (29 Si NMR) were used to confirm and determine the presence of silicone in the synthesized polymers. Thermal behavior was studied by thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). Antibacterial activity of the polymers was screened against three different strains of bacteria, namely Escherichia coli E266, Staphylococcus aureus S276 and Salmonella choleeraesuis 10708.
