摘要 |
Novel esters of pentavalent phosphorus acid having the formula
<CHEM>
wherein R and R min are haloalkyl containing from 2 to 6 carbon atoms and from 1 to 6 halogen atoms; n is an integer of from 1 to 3; each X is independently selected from hydrogen, halogen, alkyl, or hydroxyl, provided that at least one X is hydroxyl. The above compounds are effective reactive flame retardants in polyurethane and polyester polymeric compositions. |
