Abstract:
1. A composition comprising a polymer with infrared-reflective clusters dispersed therein, wherein the infrared-reflective clusters comprise titanium dioxide primary particles and a precipitate, wherein the titanium dioxide primary particles are cemented together with the precipitate to form the infrared-reflective clusters, wherein the titanium dioxide primary particles have an average particle diameter in a range of from about 0.15 to about 0.35 micron microns, and the infrared-reflective clusters of titanium dioxide primary particles have a geometric mass mean cluster diameter in a range of from about 0.38 to about 5 microns and a geometric standard deviation (GSD) in a range of from about 1.55 to about 2.5.
