    摘要: Triazolopyrimidines of the formula I ##STR1## in which R.sup.1 denotes CN, alkylsulphonyl, arylsulphonyl or arylR.sup.2 denotes H, alkyl or alkythio,R.sup.3 denotes alkyl, aralkyl, substituted aralkyl, alkenyl or alkynyl,R.sup.4 denotes alkyl, aralkyl or aryl, andR.sup.5 denotes alkyl, aralkyl or aryl, orR.sup.4 and R.sup.5, together with the carbon atom, denote a carbocyclic 5-, 6- or 7-membered ring which may be substituted or bridged,in which R.sup.4 cannot be methyl or aryl when R.sup.1 represents CN, R.sup.2 represents H, R.sup.3 represents methyl and R.sup.5 represents methyl or aryl, and in which alkyl preferably has 1-9 C atoms and aryl preferably has 6-12 C atoms, and also a process for their preparation, and their use as initiators.
