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).

摘要: Low density rigid foamed polyphosphazene articles having excellent physical and flammability properties are made by masticating a mixture of high molecular weight linear polyphosphazene, a curing agent (e.g., sulfur), an accelerator, a blowing agent and optionally fillers, processing aids and the like to form a substantially homogeneous blend and then stopping the masticating, heating to pre-cure and then heating to activate the blowing agent and complete the cure thereby forming a flexible foamed polyphosphazene composite, forming the flexible foamed polyphosphazene composition into a shaped composition, and thereafter heating the flexible foamed shaped polyphosphazene composition at a temperature and for a length of time which causes the flexible foamed polyphosphazene composition to become a rigid foamed polyphosphazene composition of the same shape as the flexible foamed polyphosphazene composition.
