Abstract

La présente invention concerne un procédé de préparation d'un bis-diphénolcarbonate de polyesterdiol soumis à allongement de chaînes par des groupes carbonate. Ce procédé consiste à chauffer un polyesterpolyol présentant un poids moléculaire moyen en nombre Mn supérieur à 250 avec un carbonate de diaryle à une température de 100-200 degrés C, sous un vide inférieur à 35 mm Hg, en présence d'un catalyseur, en utilisant moins de 1 mole de carbonate de diaryle par mole de groupes OH du polyesterpolyol, à séparer par distillation le composé arylcarbonate hydroxylé obtenu, le bis-arylcarbonate de polyesterdiol, allongé par des groupes carbonate, obtenu, étant ensuite chauffé avec un diphénol, à une température de 100-200 degrés C, sous un vide inférieur à 35 mm Hg, en présence d'un catalyseur, en utilisant plus de 1 mole de diphénol par mole de groupe carbonate d'aryle du bis-arylcarbonate de polyesterdiol, allongé par des groupes carbonate, et le composé arylcarbonate hydroxylé obtenu étant séparé par distillation. On obtient ainsi des polyesterpolycarbonates séquencés de haut poids moléculaire, à deux phases.The present invention relates to a process for the preparation of a polyesterdiol bis-diphenolcarbonate subjected to chain extension by carbonate groups. This process consists of heating a polyesterpolyol having a number average molecular weight Mn greater than 250 with a diaryl carbonate at a temperature of 100-200 degrees C, under a vacuum of less than 35 mm Hg, in the presence of a catalyst, in using less than 1 mole of diaryl carbonate per mole of OH groups of the polyesterpolyol, to separate by distillation the hydroxylated arylcarbonate compound obtained, the bis-arylcarbonate of polyesterdiol, elongated by carbonate groups, obtained, then being heated with a diphenol, to a temperature of 100-200 degrees C, under a vacuum of less than 35 mm Hg, in the presence of a catalyst, using more than 1 mole of diphenol per mole of aryl carbonate group of the polyesterdiol bis-arylcarbonate, elongated by carbonate groups, and the resulting hydroxylated arylcarbonate compound being separated by distillation. High molecular weight, two-phase, block polyesterpolycarbonates are thus obtained.
