PROCEDURE

实验过程

The liquid, organic acid anhydrides which are used as epoxy resin curing agents in carrying out the invention, include 1-methyl hexahydrophthalic anyhydride, 1-methyltetrahydrophthalic anhydride, NADIC anhydride, NADIC methyl anhydride, and the like liquid anhydrides; and blends of hexahydrophthalic anhydride, tetrahydrophthalic anhydride, phthalic anhydride, pyromellitic dianhydride, polyazelaic polyanhydride, the reaction product of trimellitic anhydride and a glycol, and benzophenone tetracarboxylic acid dianhydride solids with any of the above liquid anhydrides, to provide a liquid admixture of anhydrides. The anhydrides may be used singly or in admixture but the resultant material must be a liquid.
