Phosphorylated polyol, oligomer therefrom, polymer therefrom, processes for preparing them and their uses

摘要

Phosphorus polyol contains at least two terminal phosphate groups; or phosphonate groups; or one phosphate and one phosphonate group. Independent claims are also included for method for preparing said polyol; use of said polyol as additive in composition which is crosslinked by irradiation; oligomer obtained by reacting said polyol with polyisocyanate and hydroxylated acrylate; polymer obtained from said oligomer; and use of said polyol, polymer or oligomer in coatings or flame retardant compositions.
