| 摘要 |
<p>Catalyst for the reaction of primary cyclic mono-di-and polyimides with an oxirane oxygen cpd. esp. for prepn. of resin prepolymers, consists of a chromium (III) tricarboxylate with unoccupied coordination places. No water or other by-prods. is formed in the reaction. The prepolymers can thus be used directly for prodn. of fibre-reinforced structures.</p> |
