Abstract
The current invention treats .alpha.-octogene which, with the aid of a new procedure, has been coated with synthetic materials in such a manner that it does not convert into .beta.-octogene at room temperature The coating is done at temperatures between 30.degree. and 60.degree. C. from an aqueous slurry; this causes granulates to form which can be heated to temperatures of 100.degree. C. without a rearrangement to .beta.-octogene to occur; even a grain growth does not take place. The granulates according to the invention are pourable and can be easily dosaged. .beta.-octogene can be coated in the same manner, particularly if it is coated as very fine grain of less than 50 .mu.m according to the invention. Thus, the current invention includes also the particularly fine .beta.-octogene, coated according to the current procedure, which shows the same properties as the required .alpha.-octogene.
