Abstract: A method of preparing bio-polyols from epoxidized fatty acid esters, wherein the bio-polyols are synthesized via hydroxylation with epoxidized fatty acid esters and ring-opening reagent, using the acidic ionic liquids as catalysts. The bio-polyols are used to synthesize bio-polyurethane and bio-polyurethane foams. The acidic ionic liquids in this process is used in esterification, epoxidation, and ring-opening reaction to synthesize bio-polyols. The ionic liquids catalysts have several advantages such as easy to separate, reusable, and may reduce pollution.

Abstract: Synthesizing bio-plasticizers with acidic ionic liquids as catalysts. The acidic ionic liquids are Bronsted acidic ionic liquids, which are composed of alkyl sulfone pyridinium and strong Bronsted acid. Epoxidized fatty acid alkyl esters could be obtained via epoxidation of fatty acid alkyl esters using the acidic ionic liquids as catalysts. The epoxidized fatty acid alkyl esters perform well as bio-plasticizers, which could be substituted for phthalate ester plasticizers. The acidic ionic liquids catalysts provide good catalytic performance, are easy to separate, reusable, and may reduce corrosion of pipelines.

Abstract: A silicon resin composition, transparent optical film, and packaging materials manufactured thereby are provided. The silicon resin composition has (A) silicone and (B) metal oxide-polymer oligomer particles. The (B) metal oxide-polymer oligomer particles are in the amount of 0.5 to 5 wt % of the total weight of the silicon resin composition. The silicon resin composition has the property of low thermal stress, high refractive index, transparency, heat resistance and good adhesion, and can be widely used in different applications.
