SILYLATED 2-(2-HYDROXYPHENYL)-4,6-DIARYL-1,3,5-TRIAZINES |
| 摘要 |
2-(2-Hydroxyphenyl)-4,6-diaryl-1,3,5-triazines, which carry in the 4-position of the 2-hydroxyphenyl radical a silyl group linked through oxygen to the phenyl nucleus, as well as condensation products whose <IMAGE> units contain 2-(2-hydroxyphenyl)-4,6-diaryl-1,3,5-triazines in the side-chain, are UV absorbers which are suitable for use as stabilizers for organic polymers.
