Conformément à l'invention on dissout 3 parties de résine

resins are not directly usable, or are unusable for many purposes, for which they would otherwise be suitable and for which it would even be desirable to use them because of their relatively low price * A process for improving resins of high quality is already known.

Solvents containing methane is treated in paraffinic or saturated hydrocarbons, low boiling point, under pressure, with methane or gases containing methane. Has effect
pressures of up to. 120 atmospheres

Unlike this known process, the present invention relates to a process for the selective preparation of oouma- resins.
<EMI ID = 11.1>
to obtain from the latter, by precipitation of the dark constituents, the light constituents of the species of indene.
In accordance with the invention, 3 parts of resin are dissolved

it is also suitable, thanks to its inoombustibility, as a plaster = for premises-) where there is a danger of fire *;
