Polyolefin bound ultraviolet light absorbers |
| 摘要 |
Oligomeric materials contain ultraviolet light absorbing compounds that are covalently bound to the oligomer backbone through an ester or amide linkage. These ultraviolet light absorbing oligomers may be combined with polymers such as polyolefins to provide protection against the harmful effects of ultraviolet light.
