Low molecular weight monoalkyl phosphinate and phosphonate copolymers. |
| 摘要 |
<p>Monoalkyl phosphinate and monoalkyl phosphonate derivatives of low molecular weight water soluble polymers are prepared by copolymerizing hypophosphorous acid, monoethylenically unsaturated monocarboxylic acid(s) and an effective amount of a C3-C8 monoethylenically unsaturated dicarboxylic acid. At least 40 percent of the incorporated phosphorous is present as polymeric monoalkyl phosphinate and polymeric monoalkyl phosphonate.</p> |
