Poly(ethylene terephthalate) (pet) copolymers containing both 1,4-cyclohexanedimethanol and isophthalic acid moieties |
摘要 |
This invention relates to PET copolymer composition that have both 1,4-cyclohexanedimethal (CHDM) and isophthalic acid moieties copolymerized. These compositions have better oxygen and carbon dioxide barrier properties than either PET homopolymer or CHDM-modified PET copolymers. These copolymer compositions are useful for packaging applications (such as carbonated soft drink bottles) requiring barrier properties to oxygen and carbon dioxide at least as good or better than PET homopolymer. |
