| 摘要 |
The present invention is directed towards phosphorous containing organic materials, processes for making them and uses thereof. These materials preferably impart and/or exhibit resistance to attack, for example they may be useful as flame retardant additives and/or materials. The materials are especially radiation-curable polyester polymers. The phosphorous component used has at least one P-C bond resistant to hydrolysis or transesterification. It can be bis(hydroxymethyl)isobutylphosphineoxide, bis(hydroxypropyl)isobutylphosphine oxide and trishydroxymethylphosphine oxide.In other embodiments, it is 9,10-dihydro-9-oxa-10-phosphaphenantrene- 10- oxide.
