| abstract |
New initiators which are suitable for cationic polymerization have the following structure: such that following apply: R1 and R2 are alkyl or cycloalkyl or they, together with the S atom, form a heterocyclic ring, R3 is H or alkyl, R4, R5, R6, and R7 are H, alkyl, or alkoxy, X- is a non-nucleophilic anion. Reaction resin mixtures with initiators of this type contain, in addition to a cationically polymerizable monomer and/or oligomer, 0.01 to 10% by mass of the initiator. |
