FIELD: chemistry.
SUBSTANCE: invention relates to composite materials based on aromatic crystalline polyether ether ketone – super-structural thermoplastic and can be used in machine building, electrical engineering and electronics, nuclear industry, aircraft and helicopter building and other industries. Heat-resistant polymer composition based on a mixture of two polyester ether ketones includes a basic crystalline polyether ether ketone – product of reaction of hydroquinone and difluorobenzophenone and amorphous polyether ether ketone, in form of a product of reacting difluorobenzophenone and 4,4'-oxyphenylhexafluoropropane.
EFFECT: invention improves the relative elongation at stretching while maintaining the melting point at the level of crystalline polyether ether ketone and homogeneity of properties throughout the volume of articles.
