- 摘要：
- Fire-retardant phosphorus oligomers having -O-C-C-O- linkages between phosphorus atoms are formed by condensation of beta -haloalkyl esters of pentavalent phosphorus acids. These condensates contain cyclic 5-membered phosphorus esters whose rings can be opened by reaction with water or an alcohol. By choice of the appropriate OH-containing reactant, desired endgroup functionality can be imparted to the condensate product.
