RESINES THERMOSTABLES A BASE DE POLYIMIDE, D'ALDEHYDE-AZINE ET DE POLYAMINE |
摘要 |
<p>New heat-stable resins are provided having good mechanical and electrical properties combined with chemical inertness at temperatures of 200 DEG to 300 DEG C, which resins are resins of a three-dimensional polyimide which is obtained by reacting, at between 50 DEG C and 350 DEG C, a bis-imide of the general formula: <IMAGE> in which Y denotes H, CH3 or Cl, and A represents a divalent organic radical possessing at least two carbon atoms, a polyamine of the general formula:</p> |
