摘要：The invention relates to a compound of formula (I), characterised by thecharacteristic signals in the X-ray diffraction powder pattern measured with Cu Kalpharadiation (0.154 nm) at a 2-theta angle of 15.0 and 22.7 with a high intensity, and of 5.0,11.3, 18.9, 20.8, 21.6 and 23.6 with a medium intensity, as well as to a method for
producing the compound of formula (I) by reacting at least one isophthalic acid diester offormula (II) where R1 and R2 are the same or different and stand for an aliphatic group,with two equivalents 4-amino-2,2,6,6-tetramethylpiperidine, in the presence of at leastone catalyst from the group of metal alcoholates and at a reaction temperature ofbetween 50 and 150° C.
