OLIGOESTER-POLYOLES OF POLYETHYLENEFTALATE WASTE AND RENEWABLE MATERIALS, THE PROCESS FOR THEIR OBTAINING AND COMPOSITION FOR STRAW POLYURETHANE FOAM, CONTAINING OLIGOESTERS-POLYOLES RESULTS |
| abstract |
The invention relates to oligo-polyols, a process for making and a composition thereof based on polyurethane foams. The oligoester polyols according to the invention are composed of 25 ... 27% of structural units of aromatic carboxylic acids, 8-10% of aliphatic dicarboxylic acid units of 4 ... 6 carbon atoms, 63 ... 68% of units structural aliphatic diols or linear or branched oxyalkylenediols with 2-6 carbon atoms, 6-7% aliphatic oxyalkylene polyol units with 4 ... 6 primary hydroxyl functions and 8 ... 12% gravimetric vegetable oil. The process according to the invention consists in the degradative transesterification of PET waste in the presence of a mixture of diols and vegetable oil as well as an organic catalyst at a maximum temperature of 180 ° C followed by esterification of the products with mixtures of aromatic and dicarboxylic acids aliphatic at 205 ° C and atmospheric pressure. The composition according to the invention contains 20 ... 55% oligoester polyols, as well as common processing ingredients. |
