- Example 11 Hydrolysis of phosphites (weight gain) depending on the
- phosphites The hydrolysis of phosphites involves the absorption of water (e.g. from atmospheric humidity). Thus, phosphites absorb water on the one hand during storage, but on the other hand also in incorporated form in the polymer and become ineffective with increasing hydrolysis. This hydrolysis can be visualized by observing the water absorption of a phosphite by weight gain. For this purpose, an amount of 125 g of bis- (2,4-di-tert-butylphenyl) pentaerythritol diphosphite ( ⁇ Weston 626, Borg Warner) is stored open in a climate room at 23 ° C. and a relative air humidity of 50%.

Both samples were in the form of crystal powder.
- Bis- (2,4-di-tert-butylphenyl) pentaerythritol diphosphite takes up 3 g of water over a period of 21 days; However, the mixture of bis (2,4-di-tert-butylphenyl) pentaerythritol diphosphite and the stabilizer from Example 1 only takes up 2 g of water. This proves that the stabilizer from Example 1 significantly reduces the tendency to hydrolysis of phosphites.
