Dienophile additives to polyvinylidene chloride copolymers |
abstract |
A flexible film for packaging articles such as food is provided. The film comprises a layer of polyvinylidene (“PVdC”) homopolymer, polyvinylidene and methyl acrylate (“PVdC-MA”) copolymer or other polyvinylidene chloride copolymer. A dienophile such as, for example, ethyl trans-cinnamate, methyl trans-cinnamate, dibutyl maleate, dimethyl maleate or maleic anhydride is blended with the PVdC polymer or PVdC-MA copolymer to reduce yellowing of the film caused by degradation of the PVdC or PVdC-MA through heat or electron beam irradiation. Preferably a range of about 0.05% and about 5% by weight of the dienophile is added to the PVdC or PVdC-MA. |
