Functionalised oxacalixarenes, their preparation and use in instant adhesive compositions.

摘要

Oxacalixarenes of general formula I:- <CHEM> wherein m = 0 - 7 and n = 1 - 8 with the proviso that m + n </= 8; R is hydrogen, halogen, or hydrocarbyl, aryl, hydrocarbylaryl or a substituted derivative thereof, and R may be the same or different on each aryl group; and R' is hydrocarbyl, aryl hydrocarbylaryl, hydrocarbyloxy, aryloxy or hydrocarbylaryloxy or a substituted derivative thereof. The invention also provides a method of preparing oxacalixarenes of formula I, and cyanoacrylate adhesive compositions including as accelerator an oxacalixarene of formula I.
