| titleOfInvention | Process for the preparation of linear high-molecular saturated polyesters |
| abstract | a) zunächst mit einer Teilmenge von 70 bis 95 Gewichtsprozent des Polyestervorkondensats die Kondensation beginnt und b) nach Ablauf von 10 bis 50% der Gesamtkondensationsdauer der gemäß a) kondensierenden Polyesterschmelze die restlichen 5 bis 30 Gewichtsprozent des Polyestervorkondensats zu der kondensierenden Polyesterschmelze zugibt und zu Ende kondensiert. Production of high molecular weight linear saturated polyesters, which are derived from dicarboxylic acids or their ester-forming derivatives and aliphatic and / or cycloaliphatic diols, by condensing polyester precondensates with a relative viscosity of 1.05 to 1.15 at temperatures of 220 to 280 ° C. under reduced pressure , where one a) the condensation begins with a portion of 70 to 95 percent by weight of the polyester precondensate and b) after 10 to 50% of the total condensation time of the polyester melt condensing according to a), the remaining 5 to 30% by weight of the polyester precondensate is added to the condensing polyester melt and condensed to the end. |
