New (meth)acrylic acid thio:octanoyl:oxy:alkyl ester(s)

摘要

(Meth)acrylic acid thiooctanoyloxyalkyl esters (I) are new. R1 = H or 1-3C alkyl; R2 = 1-30C opt. substd. 1-30C alkylene. Pref. (I) is prepd. by carrying out reaction in the presence of a catalyst, p-toluenesulphonic acid, benzenesulphonic acid or N,N'-dicyclohexylcarbodiimide. The adhesive compsn. comprises a cpd. (I) and an organic solvent and/or a radical-polymerisable monomer and/or a polymerisation catalyst. (I) pref. has a wt. ratio to solvent and/or monomer of 1:10000 to 1:5, esp. 1:5000 to 1:500.
