| 摘要 |
The present invention relates to a stabilizer mixture prepared by partially condensing PCl3 with 2,2'-dimethyl-4,4'-dihydroxy-5,5'-di-tert-butyldiphenyl sulfide, where the phosphorus content is from 2 to 4% by weight and the content of 2,2'-dimethyl-4,4'-dihydroxy-5,5'-di-tert-butyldiphenyl sulfide is from 0.5 to 50% by weight.The stabilizer mixture has very good solubility in organic solvents and in the polymer and has very good stabilizing action.
