| description | A phosphorus-containing polymer is provided comprising the reaction product of a chain-transfer agent having at least one pH bond with an unsaturated carboxylic, phosphonic or sulphonic acid. The invention also provides the aforementioned phosphorus-containing polymer further comprising phosphorus-containing end-caps. The polymers have a biodegradability of at least 20% per 28 days (as determined by OECD 306). |
