Abstract
Sposób wytwarzania poli(estro-węglanów) polega na tym, że węglan dimetylu poddaje się reakcji z α,ω-diolem, w obecności katalizatora transestryfikacji, przy czym stosuje się 7-10-krotny nadmiar molowy węglanu di metylu. Otrzymany bis(metylowęglan)alkilenu poddaje się reakcji z estrem dimetylowym lub dietylowym kwasu dikarboksylowego lub ich mieszaniną w stosunku molowym od 1:9,5 do 9,5:1 i α,ω-diolem w stosunku molowym od 1,5:1-2:1 do sumy moli obu składników kwasowych, przy czym reakcję polikondensacji prowadzi się najpierw w temperaturze 150-200°C, w przepływie azotu pod normalnym ciśnieniem, a następnie po odebraniu powyżej 95% teoretycznej ilości metanolu lub etanolu lub ich mieszaniny, pod zmniejszonym ciśnieniem w temperaturze nieprzekraczającej 220°C.The method of producing poly(ester-carbonates) consists in reacting dimethyl carbonate with α,ω-diol in the presence of a transesterification catalyst, wherein a 7-10-fold molar excess of dimethyl carbonate is used. The obtained alkylene bis(methylcarbonate) is reacted with a dimethyl or diethyl ester of a dicarboxylic acid or a mixture thereof in a molar ratio of 1:9.5 to 9.5:1 and α,ω-diol in a molar ratio of 1.5:1-2:1 to the sum of moles of both acid components, wherein the polycondensation reaction is carried out first at a temperature of 150-200°C, in a nitrogen flow at normal pressure, and then after removing more than 95% of the theoretical amount of methanol or ethanol or their mixture, under reduced pressure at a temperature not exceeding 220°C.
