HEAT AGING-RESISTANT POLYAMIDES WITH FLAME RETARDANCE Russian patent published in 2015 - IPC C08K3/08 C08K3/28 C08K3/32 C08J5/00 C08L77/00 

FIELD: chemistry.

SUBSTANCE: invention relates to thermoplastic moulding compounds. Described are thermoplastic moulding compounds, comprising: A) 10 to 98 wt % of a polyamide; B) 0.001 to 20 wt % of iron powder with particle size of at most 10 mcm (d₅₀ value) and with a specific BET surface area of 0.1 to 5 m²/g according to DIN ISO 9277; C) 1 to 40 wt % of a halogen-free flame retardant from a group of the phosphorus- or nitrogen-containing compounds or P-N condensates, or a mixture thereof; and D) 0 to 70 wt % of other additives, where the total of the percentages by weight of components A) to D) is equal to 100%. The invention also describes use of said thermoplastic moulding compounds in making fibres, films and moulded articles, and fibres, films and moulded articles made from the thermoplastic moulding compounds.

EFFECT: providing thermoplastic polyamide moulding compounds, having improved heat aging resistance and good surface quality after heat aging, as well as mechanical properties.
