1,5,7-Triazabicyclo[4.4.0]dec-5-ene (TBD)-catalyzed polycondensation reactions of fatty acid derived di-Me dicarbamates and diols are introduced as a versatile, non-isocyanate route to renewable polyurethanes. The key step for the synthesis of di-Me carbamate monomers from plant-oil-derived dicarboxylic acids is based on a sustainable base-catalyzed Lossen rearrangement. The formed polyurethanes with mol. weights up to 25 kDa are characterized by SEC, DSC, and NMR anal. via size exclusion chromatog. (SEC), differential scanning calorimetry (DSC) and NMR. In the experiment, the researchers used many compounds, for example, Dimethyl decanedioate (cas: 106-79-6Quality Control of Dimethyl decanedioate).
Dimethyl decanedioate (cas: 106-79-6) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.Quality Control of Dimethyl decanedioate
