Disclosed are oligomeric phosphonates including oligophosphonates, random or block co-oligo(phosphonate ester)s and co-oligo(phosphonate carbonate)s produced using a condensation process terminated with hydroxyl, epoxy, vinyl, vinyl ester, isopropenyl, isocyanate groups, and the like. These materials can be used as a reactive additive to other polymers, oligomers or monomer mixtures to impart flame resistance without diminishing melt processability which is important in the fabrication of polymers for many applications. 1. A composition comprising oligomeric phosphonates having a total number of termini with reactive end groups of from about 80% to 100% , wherein the each reactive end group is independently selected from hydroxyl , epoxy , vinyl , vinyl ester , isopropenyl , isocyanate , and combinations thereof.2. The composition of claim 1 , wherein each reactive end-group is hydroxyl.3. The composition of claim 1 , wherein the oligomeric phosphonates comprise an oligophosphonate claim 1 , random co-oligo(phosphonate ester) claim 1 , block co-oligo(phosphonate ester) claim 1 , random co-oligo(phosphonate carbonate) claim 1 , or block co-oligo(phosphonate carbonate).4. The composition of claim 1 , wherein the oligomeric phosphonates comprise linear oligomeric phosphonates claim 1 , branched oligomeric phosphonates claim 1 , or a combination thereof.5. The composition of claim 1 , wherein the oligomeric phosphonates comprise a number averaged molecular weight of from about 500 g/mole to about 5000 g/mole.6. The composition of claim 1 , wherein the oligomeric phosphonates comprise units derived from bisphenol.8. The composition of claim 7 , wherein —O—Ar—O— is derived from resorcinol claim 7 , hydroquinone claim 7 , bisphenol A claim 7 , bisphenol F claim 7 , and 4 claim 7 ,4′-biphenol claim 7 , phenolphthalein claim 7 , 4 claim 7 ,4′-thiodiphenol claim 7 , 4 claim 7 ,4′-sulfonyldiphenol claim 7 , 1 claim 7 ,1-bis(4-hydroxyphenyl)-3 claim 7 ,3 claim 7 ,5-trimethyl- ...
