FIELD: chemistry.
SUBSTANCE: invention relates to aromatic polyesters, in particular, to halogen-containing aromatic polyester ketones, which can be used as structural and film materials in electronics, electrical engineering, aviation, space, automotive and other industries. These halogen-containing aromatic copolyester ketones have the formula:
with a molar ratio of bisphenols from 99:1 to 1:99, where n = 1-15, m = 1-15, z=7-25.
EFFECT: expansion of the range of fire–resistant aromatic polyester ketones with increased fire, heat and thermal resistance.
