New aromatic sulfonylsulfoxonium salts are of formula ##STR1## where q is 1 to 4, R denotes an aliphatic, cycloaliphatic, or aromatic group, R.sup.6 denotes H, an alkyl or aralkyl group, or a group --COR.sup.9, --CO--NH--(CO).sub.r --R.sup.10, or --SO.sub.2 --R.sup.11, where r is zero or 1, one, but not both, of R and R.sup.6 denoting an aromatic group, R.sup.7 denotes an alkyl, alkenyl, cycloalkyl, cycloalkylalkyl, or aralkyl group, R.sup.8 has the same meaning as R.sup.7 but may alternatively represent a dialkylamino group or, if R.sup.7 denotes alkyl, it may alternatively represent an arylamino group, R.sup.9, R.sup.10, and R.sup.11 each denote an alkyl, aryl, or aralkyl radical of 1 to 25 carbon atoms, t is 1, 2, or 3, and Z.sup.- denotes a t-valent anion of a protic acid. The salts, e.g., dimethyl-p-toluenesulfonylmethylsufoxonium hexafluorophosphate, are useful as catalysts for the polymerization of cationically polymerizable materials by means of actinic radiation and/or heat. Polyepoxides and resols may be photopolymerized in the presence of the salts and subsequently crosslinked with a latent heat-curing agent.
新的芳香基磺酰亚砜盐的化学式为##STR1## 其中q为1至4,R代表脂肪族、环状脂肪族或芳香族基团,R.sup.6代表H、烷基或芳基烷基团,或羧基R.sup.9,--CO--NH--(CO).sub.r --R.sup.10,或--SO.sub.2--R.sup.11,其中r为零或1,R和R.sup.6中的一个但不是两个都代表芳香族基团,R.sup.7代表烷基、烯基、环状烷基、环状烷基烷基或芳基烷基团,R.sup.8具有与R.sup.7相同的含义,但也可以代表二烷基氨基团或如果R.sup.7代表烷基,则可以替代地代表芳基氨基团,R.sup.9、R.sup.10和R.sup.11分别代表1至25个碳原子的烷基、芳基或芳基烷基基团,t为1、2或3,Z.sup.-代表质子酸的t价阴离子。这些盐,例如二甲基对甲苯磺酰甲基亚砜六氟磷酸盐,可用作通过光致辐射和/或热催化剂催化阳离子聚合材料的催化剂。聚环氧化物和树脂可以在这些盐的存在下光聚合,随后用潜伏热固化剂交联。
