FIELD: chemistry.
SUBSTANCE: polymeric composition for cast moulding piezoelectric elements contains an epoxy diane resin, an epoxy aliphatic resin and an aliphatic amine hardener. The composition also contains polydiene-urethanediepoxide and a product of reacting lyphenylmethane diisocyanate with glycidol in molar ratio of components between 1.0-1.1 and 1.0-1.5. The polymeric composition has improved physical-mechanical and processing properties.
EFFECT: piezoelectric composites with improved dynamic characteristics are obtained from said composition.
