The present invention relates to a process for producing a FAGE-based biofuel composition, the process being characterized by an enzymatic transesterification of fatty acid alkyl esters with glycerol formal. The invention is also directed to the biofuel composition obtained by said process as well as to the uses thereof.

The invention relates to the technical field of polymer laminated materials, in particular to a PVB-PU laminated material as well as a preparation method and application thereof. The method comprises the following steps: carrying out low-temperature plasma treatment on a PVB (Polyvinyl Butyral) sheet to obtain an activated PVB sheet of which the surface is rich in active oxygen-containing groups; the preparation method comprises the following steps: mixing amino modified polyether polyol, diisocyanate, a composite cross-linking agent (glyceryl formal and pentaerythritol triacrylate) and a catalyst to obtain a PU composite system; and coating the surface of the activated PVB sheet with the PU composite system, and carrying out curing treatment to obtain the PVB-PU laminated material. The PVB surface is subjected to low-temperature plasma activation, a PU composite system formed by combining amino-modified polyether polyol and the composite cross-linking agent is adopted, chemical-physical synergistic high-strength interface bonding is achieved under the low isocyanate group / hydroxyl proportion, and meanwhile the weather resistance, the optical performance and the process stability of the material are remarkably improved.
