FIELD: chemistry.
SUBSTANCE: invention relates to polyarylene ether ketone film which can be used in various fields of technology, for instance, for obtaining flexible printed circuit boards. Moulding mass for film obtaining contains a) 60-96 wt. p. of polyarylene ether ketone, b) 2-25 wt. p. of hexagonal boron nitride, c) 2-25 wt. p. of talc, with the sum of weight components a), b) and c) constituting 100. Method of film manufacturing includes compounding by mixing said components in melt, melt extrusion by means of flat-slot device and strengthening formed by extrusion in form of cloth film by placement on chill rolls.
EFFECT: obtained film demonstrates less shrinkage and has lower coefficient of thermal surface expansion.
