Title: Polyglycidyl compounds

Abstract: 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 T.sub.g value (determined by DSC, heating rate=20.degree. C./min) higher than 20.degree. 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 ##STR1## wherein Z is a direct single bond or --O--; more than two of R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are --OH, --O--CO--R--CO--OH, --O--R--OH, --O--CO--NH--R--NH--CO--O--R--OH or --[O--C.sub.m H.sub.2m ].sub.n --OH, with the proviso that R.sub.1, R.sub.2, R.sub.3 and R.sub.4 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 C.sub.1 -C.sub.8 alkylene, C.sub.5 -C.sub.8 cycloalkylene, C.sub.6 -C.sub.14 arylene or partially hydrated C.sub.6 -C.sub.14 arylene, and the remaining R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are a hydrogen atom or --O--C.sub.1 -C.sub.8 alkyl, --O--C.sub.5 -C.sub.8 cycloalkyl, --O--C.sub.6 -C.sub.14 aryl, partially hydrated --O--C.sub.6 -C.sub.14 aryl or (meth)acrylate; and R.sub.5, R.sub.6, R.sub.7 and R.sub.8 are each independently of one another C.sub.1 -C.sub.8 alkyl, C.sub.5 -C.sub.8 cycloalkyl, C.sub.6 -C.sub.14 aryl, partially hydrated C.sub.6 -C.sub.14 aryl 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.
