POLYMERS CONTAINING DIESTER UNITS |
| 摘要 |
Polymers containing diester units of formula (I), where R1 and R2 each represents a hydrogen atom or a carbon-att- ached monovalent organic group or R1 and R2 together form a carbon-attached divalent organic group, with the proviso that where such units are attached at both ends to carbon atoms and the polymers are polyolefinic, then the polymers are biode- gradable and/or are water-swellable and/or are associated with a biologically active or diagnostic agent.
