NAPHTHOFURANYLNAPHTHOL STABILIZERS |
| 摘要 |
<p>Naphthofuranylnaphthols are produced by (1) reacting glyoxal with a naphthol in the presence of an acidic catalyst to form an acetal, and (2) thereafter partially hydrolyzing the acetal with an acidic or basic catalyst. Naphthofuranylnaphthols are effective stabilizers of organic materials against the deleterious effects of oxygen, heat, and light. The stability of dienic polymers and styreneacrylonitrile copolymers is particularly enhanced by incorporating stabilizing amounts of naphthofuranylnaphthols.</p> |
