Abstract
This invention relates to a process for hardening a curable normally liquid hydrocarbon compound optionally substituted with an alkyloxy, ester aldehyde, amido, halo, sulfonate, sulfate, sulfite, mercapto or nitro group and containing at least one functional radical selected from the group of ##STR1## and EQU --(X)C.dbd.C(Z)--Y--(CH.sub.2)-- wherein Y is --O--, --S-- or --NH-- and X and Z are each independently hydrogen, alkylene having from 1 to 20 carbon atoms, aryl or a mixture thereof, which process comprises contacting said liquid for less than one minute with a hardening amount of a volatilized hard Lewis acid under anhydrous conditions and at a hardening temperature below the deformation temperature of any substrate material which may be used to support said liquid.
