摘要:
The present invention relates to opaque polymers functionalized with phosphorus acid groups, composites of TiO2 particles and the opaque polymers, and methods for their preparation. The composites are useful in coatings formulations and have been shown to exhibit improved hiding benefits in coated substrates over compositions containing non-functionalized opaque polymer and TiO2.
