Abstract

The present invention is directed towards water-thinnable phosphorous-containing polymers precursors, their preparation and use. The precursors of the invention are useful in compositions for preparing coatings which impart and/or exhibit resistance to attack, for example which are useful as flame-retardant coatings.
