    • The present invention is directed to a polyglycidyl compound having on average more than two, preferably more than two and a half, particularly preferably more than three, glycidyl groups per molecule and a Tg value (determined by DSC, heating rate=20° C./min) higher than 20° C., based on a polyfunctional 1,1′-spirobisindane of formula I or on a mixture of different polyfunctional 1,1′-spirobisindanes of the general formula I wherein Z is a direct single bond or —O—; more than two of R1, R2, R3 and R4 are —OH, —O—CO—R—CO—OH, —O—R—OH, —O—CO—NH—R—NH—CO—O—R—OH or —[O—CmH2m]n—OH, with the proviso that R1, R2, R3 and R4 are not —OH when Z is a direct single bond, wherein m is an integer from 2 to 4, n is an integer from 1 to 20, and R is C1-C8alkylene, C5-C8cycloalkylene, C6-C14arylene or partially hydrated C6-C14arylene, and the remaining R1, R2, R3 and R4 are a hydrogen atom or —O—C1-C8alkyl, —O—C5-C8cycloalkyl, —O—C6-C14aryl, partially hydrated —O—C6-C14aryl or (meth)acrylate; and R5, R6, R7 and R8 are each independently of one another C1-C8alkyl, C5-C8cycloalkyl, C6-C14aryl, partially hydrated C6-C14aryl or a hydrogen atom, for the production of moulded articles, coatings, matrix materials or adhesives. Also disclosed is the reaction product of a polyglycidyl compound based on a polyfunctional 1,1′-spirobisindane or mixture thereof with a less than stoichiometric amount of a compound containing two substitutents reacting with epoxy groups.
