| titleOfInvention | Process for the continuous production of biodegradable polyesters |
| abstract | Process for the continuous production of a biodegradable polyester based on aliphatic and aromatic aliphatic dicarboxylic acids and aliphatic dihydroxy compounds, where a mixture of aliphatic dihydroxy compounds, aliphatic and aromatic dicarboxylic acids and optionally other comonomers (component C) is combined in a paste without the addition of a catalyst or, as an alternative, the liquid esters of the dicarboxylic acids and the dihydroxy compound and optionally other comonomers, without the addition of catalyst, are supplied to the system, in which case i) in a first stage, this mixture, together with the whole amount or with a portion of the catalyst, it is esterified or setranseterified continuously; ii) in a second stage, the transesterification product or, respectively, esterification obtained according to i) is continuously pre-condensed to an intrinsic viscosity of 20 to 70 cm3 / g according to DIN 53728; iii) in a third stage, the product that can be obtained from ii) is continuously polycondensed to an intrinsic viscosity of 60 to 170 cm3 / g according to DIN 53728, and iv) in a fourth stage, the product that can be Obtained from iii) in a polyaddition reaction reacts in a continuous manner with a chain extender D up to an intrinsic viscosity of 150 to 320 cm313 / g in accordance with DIN 53728 |
