The phosphonate ester of open oligomerization, and specifically, hyperbranched oligomeric phosphonate, described hyperbranched oligomeric phosphonate includes using that condensation process produces with the oligomeric phosphonate of the endizations such as hydroxyl, epoxy, vinyl, vinyl esters, isopropenyl, isocyanate groups, randomly or the co-oligomerization of block (phosphonate ester-ester) and co-oligomerization (phosphonate ester carbonic ester).These materials are used as the reactive additive to other polymer, oligomer or monomer mixture to give flame resistance and the melt processability that do not detracts, and described melt processability is important in the manufacture for the polymer of a lot of application. |
