FIELD: chemistry. ^ SUBSTANCE: polymer composition contains a polycarbonate polymer (component A), coated hexaboride particles (component B) as well as metal nitride particles (component C). The hexaboride particles consist of particles of a hexaboride of at least one element selected from a group consisting of Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Sr and Ca and a coating layer containing a metal oxide. The composition contains particles of a nitride of a metal selected from a group consisting of Ti, Zr, Hf, V, Nb and Ta. The composition is obtained by mixing in molten state coated particles of hexaboride, metal nitride and a polymer dispersant with a polycarbonate polymer. ^ EFFECT: invention provides the article with efficient heat-reflecting properties, excellent transparency and water-resistance. ^ 13 cl, 1 dwg, 1 tbl, 5 ex |
