    • A hydroxyphenyl or alkoxyphenyl phosphine oxide composition comprises (i) a first mixture of mono-(hydroxyphenyl) or (alkoxyphenyl) phosphine oxide isomers each having the formula (I) (ii) a second mixture of bis-(hydroxyaryl) or (alkoxyphenyl) phosphine oxide isomers each having the formula (II) and (iii) a third mixture of tris-(hydroxyaryl) or (alkoxyphenyl) phosphine oxide isomers each having the formula (III) wherein R is hydrogen or an alkyl group containing from 1 to 6 carbon atoms, R 1 and R 2 are the same or different and each is an alkyl group containing from 1 to 6 carbon atoms, and each of x and y is an integer between 0 and 4. Each OR group is in the ortho or para position with respect to the bond between the P atom and the associated phenyl group such that, for each mixture (i), (ii) and (iii), the ratio of the number of OR groups in the ortho -position with respect to the bond between the P atom and the associated phenyl group to the number of OR groups in the para -position with respect to the bond between the P atom and the associated phenyl group is between about 50:50 and about 0.1:99.9.
    • 羟基苯基或烷氧基苯基氧化膦组合物包含(i)具有式(I)的单(羟基苯基)或(烷氧基苯基)氧化膦异构体的第一混合物(ii)双 - (羟基芳基)或(烷氧基苯基) 各自具有式(II)和(iii)的三氧化膦异构体,各自具有式(III)的三 - (羟基芳基)或(烷氧基苯基)氧化膦异构体的第三混合物,其中R是氢或含有1至6的烷基 碳原子,R 1和R 2相同或不同,并且各自为含有1至6个碳原子的烷基,并且x和y各自为0至4之间的整数。每个OR基团在邻位或对位具有 相对于P原子和相关苯基之间的键,使得对于每种混合物(i),(ii)和(iii),邻位的OR基数相对于键之间的键的比例 P原子和相关苯基与对位中OR基团的数目 相对于P原子和相关苯基之间的键在约50:50至约0.1:99.9之间。
