    • A poly(hydroxy ester ether) is prepared by reacting a) a diacid containing a hetero moiety of the formula:HO.sub.2 CCH.sub.2 X(RX).sub.y CH.sub.2 CO.sub.2 Hwherein X is selected from the group consisting of --O--, --S--, and NH; y is the whole number 0 or 1; and R is selected from the group consisting of an aromatic moiety and a heterocyclic moiety having from 6 to 30 carbon atoms; andb) a diglycidyl ether generally represented by the formula: ##STR1## wherein R.sup.2 is an aromatic moiety or divalent aliphatic hydrocarbon having 2 to 20 carbon atoms. Films, articles and laminations made from the composition exhibit an oxygen permeability of less than about 8 cc-mil/100 in.sup.2 -24 hour-atmosphere. The present invention is further directed to a miscible blend having the poly(hydroxy ester ether) of the present invention and a second component selected from a saturated polyester of an aromatic diacid, such as PET and PEN.
    • 通过使a)含有下式的异质部分的二酸反应制备聚(羟基酯醚):HO2CCH2X(RX)yCH2CO2H其中X选自-O - , - S - 和NH; y是整数0或1; 并且R选自芳族部分和具有6至30个碳原子的杂环部分; 和b)一般由下式表示的二缩水甘油醚:其中R2是芳族部分或具有2-20个碳原子的二价脂族烃。 由组合物制成的薄膜,制品和叠片在2-24小时的气氛中显示小于约8cc密耳/ 100的氧气渗透性。 本发明还涉及具有本发明的聚(羟基酯醚)和选自芳族二酸的饱和聚酯如PET和PEN的第二组分的可混溶共混物。
