Abstract (en)

[origin: WO9903851A1] 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 DEG C/min) higher than 20 DEG C, based on a polyfunctional 1,1'-spirobisindane of formula (I) or on a mixture of different polyfunctional 1,1'-spirobisindanes of 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, 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.
