Flame retardants (FRs) are used for in protection against fire. Organic–inorganic hybrids could become one of the most promising FR solution in the future. In this paper, the synthesis, the characterization and the use as FRs and filler of grafted titania and alumina with 2‐chloroethylphosphonic acid are presented. These hybrids contain 3.8–3.24% P and have good flame retardance when they are incorporated into unsaturated polyester resins. Alumina treated with 2‐chloroethylphosphonic acid performed better than titania. The advantage of this approach is the use of these hybrid materials as filler and FR, in the same time, and the increase in flame retardancy by synergistic effect between alumina phosphorus and chlorine, for unsaturated polyester resins.
