FIELD: chemistry.SUBSTANCE: invention relates to production of plastic package and is intended for producing bottles and preforms for bottles from a polymer composition. Composition contains a polymer matrix, which is a polyester, selected from a group consisting of polyethylene terephthalate and polyethylene terephthalate copolymers, oxidation catalyst, selected from a group consisting of a transition metal compound, molecules, including N-hydroxy cyclic imide, derivatives and combinations thereof. Composition also contains a copolymer or oligomer, including at least one comonomer containing allyl carbon atoms, and at least one polar fragment. At least one comonomer containing allyl carbon atoms, is butadiene or isoprene. Polar fragment is p-aminobenzamide and is nonreactive capable relative to polyester matrix. Composition can be granulated or a product, such as preform, can be obtained directly therefrom.EFFECT: invention allows to produce transparent (relatively free from turbidity) preforms and bottles with good impermeability for oxygen.11 cl, 2 dwg, 2 tbl |
