Polymers are rendered more resistant to oxidation by the incorporation of a compound containing at least one phosphate grouping in which the phosphorus atom and at least two of the three oxygen atoms attached thereto by single covalent bonds form part of a cyclic structure, the remaining atoms in the ring being carbon atoms, such that when only two of the three said oxygen atoms form part of a cyclic structure the third said oxygen atom is attached to hydrogen, a metal, a metalloid group, an alkyl or substituted alkyl radical or a hindered aryl radical. The compound may be formed in situ in the polymer from a precursor in which one of the -C-O-P- links of the cyclic structure is replaced by -C-OH HO-P-, or from an organo-soluble metal salt and a hydroxyphosphate corresponding to the antioxidant.
聚合物呈现抗氧化的掺入磷酸化合物包含至少一个分组的磷原子和至少两三个氧原子附具的由单一的共价键形成一个循环结构的一部分,剩下的原子环碳原子,这样当只有两三个氧原子形成环状结构的一部分,第三个说氧原子与氢,金属,非金属组,烷基基或取代的烷基基或受阻芳基该化合物可由环结构的- c - o- p -链中的一个被- c - oh - ho -取代的前体在聚合物中原位形成，或由有机可溶性金属盐和与抗氧化剂对应的羟基磷酸盐形成。
