Abstract
In the early 1980s Rohm & Haas Company in the USA successfully developed the technology to manufacture single-void polymer microspheres. These microspheres are marketed as Ropaque® Opaque Polymer. On drying, the liquid irreversibly evaporates out of the void and is replaced by air, thus yielding a small particle with the capacity of internal reflection and scattering of light. This is due to the large difference in refractive index between the hard polystyrene polymer in the shell and the air in the void. The invention has led to what is now significant use of microvoid polymers in surface coatings.
