Radiation-chemical cross-linking of solid epoxycinnamic resin and its base compositions

A study was made on some properties of three-dimensional product on the base of EHKS-20 oligomer and its compositions with EHAS-8A oligomer, as well as on possibility of stabilizing the process of radiation cross-linking of this oligomer. Absorbed radiation dose, equal to 1.6 MGy was required for total cross-lingking of EHKS-20 aligomer in electron accelerator and 0.8-1.2 MGy - for composition. Polymer thermal stability, soffening point, obtained during uniaxial sample straining, were evaluated. Radiation cross-linked EHKS-20 oligomer and its compositions are characterized by high dielectric properties and wet strength. Radiation cross-linking of oligomers can be sensitized by additions of maleic acid imides
