THERMOPLASTIC MOULDING COMPOUNDS CONTAINING ORGANIC BLACK PIGMENTS Russian patent published in 2012 - IPC C08K5/3447 C09B5/62 C08L71/12 C08L81/02 F21V7/22 C08K5/34 C08L79/04 C08L69/00 

FIELD: chemistry.

SUBSTANCE: moulding compounds contain a component (A) of 34-99.99 wt % of at least one thermoplastic polymer selected from (i) polyarylene ethers, (ii) polyether imides, (iii) polyarylene sulphides, (iv) polycarbonates with glass-transition temperature of at least 145°C, and copolymers of said polymers (i)-(iv); a component (B) of 0.01-10 wt % of at least one organic black pigment which is transparent in the range from 1000 nm to 1600 nm and has thermal stability according to DIN EN 12877-1 of at least 300°C. The moulding compounds can optionally contain 0-6 wt % of a lubricant (C), 0-50 wt % of one or more additives (D). The sum of all components is equal to 100 wt %.

EFFECT: reducing heat accumulation in structural components made from synthetic materials, moulded articles, films and membranes.
