摘要： A melt polymerization process for the preparation of poly(1,3-propylene-co-isosorbide) terephthalate (3GIT), new 3GITs and products made from the 3GITs. The process comprises (a) providing a mixture comprising terephthalic acid or its alkyl ester, 1,3-propanediol and isosorbide in a molar ratio of diols to terephthalic acid or its alkyl ester of from about 1.1:1 to about 1.6:1 and a molar ratio of 1,3-propanediol to isosorbide of from about 2:1 to about 10:1; (b) reacting the mixture in an inert atmosphere at a temperature of about 180 to about 245° C., with concurrent removal of a distillate comprising at least 80% of the water or alkanol volatile reaction product, wherein the distillate contains less than about 5 weight % 1,3-propanediol and less than 1 weight % isosorbide; and (c) continuing the reaction in the presence of a polycondensation catalyst at a pressure of about 0.25 to about 2 mm Hg and about 245 to about 260° C. to form a 3GIT containing about 4 to about 20 mole % isosorbide units, based on the 3GIT.
