Polymeric-containing compositions having improved oxidative stability nhave the polymer and at least two stabilizing agents. These agents are nselected from low temperature antioxidants such as alkali metal and alkaline nearth metal hypo or hydrogen phosphites, high temperature antioxidants such nas: alkali metal or alkaline earth metal phenylphosphonates, thioethers like ndialkyl thioalkylionate and polymers thereof and metal deactivating agents nlike polydentate ligands and ethylene diamine-tetracidic acid compounds. The ncomposition can be a coating composition for substrates including those like nfibrous material including fibers, bundles of fibers, strands, roving, flakes nand beads. The composition can be present as a dried residue on the nsubstrate. For fibrous substrates, the composition also has at least one norganofunctional silane coupling agent, may also have processing aids such as nepoxy polyester polymers and/or lubricants. In addition, the npolymeric-containing composition can have a crosslinking agent in an effective namount to produce a dried residue of limited swellability from the composition. |
