Polyols from renewable resources

Polybutadiene polyols 5. Polyols from renewable resources... [Pg.50]

By chemical recovery of polyester [poly(ethylene terephthalate) (PET)] (Chapter 16) and PU wastes, by alcoholysis or by aminolysis (Chapter 20), new polyols are obtained that can be used in rigid PU foam fabrication. The vegetable oil polyols, obtained by chemical transformation of the double bonds in vegetable oils in various hydroxyl groups are a very attractive route to obtain polyols from renewable resources (Chapter 17). [Pg.318]

An important development in the area of polyols from renewable resources was realised by transformation of the dimeric or trimeric acids (or of corresponding methyl esters) by hydrogenation in C36 diols or C54 triols. [Pg.466]
