  • Substantially crystalline poly(alkylene carbonates), laminate and methods of making
    Patent number: 5536806
    Abstract: Disclosed are oriented poly(alkylene carbonates) useful in packaging film for food and other oxygen effected substances. These oriented polymers include poly(alkylene carbonates) with substantial crystallinity. Also disclosed is the crystallization of amorphous poly(alkylene carbonates) by stretching or orienting them. Further disclosed are (1) a high oxygen barrier, high clarity laminate resistant to delamination, that has a layer comprising an oriented, low oxygen barrier, predominantly crystalline polymer, and another layer adherent directly or indirectly thereto and comprising an oriented poly(alkylene carbonate) preferably with substantial crystallinity; and (2) a method for making the laminate from the polymer and the amorphous counterpart of the poly(alkylene carbonate).
