UV stable compositions |
摘要 |
This invention relates to a method for increasing the ultraviolet light stability of articles made from macromolecular materials comprising: forming a flame-retarded formulation containing macromolecular material and a mixture of (i) a first alkylenebis(tetrabromophthalimide) flame retardant having a yellowness index (YI) value ranging from about 20 to about 40 as determined by ASTM D-1925; and (ii) a second alkylenebis-(tetrabromophthalimide) flame retardant having a yellowness index (YI) value (ASTM D-1925) ranging from about 2 to about 15 whereby the uv stability of a test plaque made from the flame-retarded formulation is greater than the arithmetic average of the uv stabilities of a test plaque made from a flame-retarded formulation containing (i) but not (ii) and of a test plaque made from a flame-retarded formulation containing (ii) but not (i).
