Abstract
The invention provides 2-hydroxypropane sulphonic acid derivatives of general formula ##STR1## wherein n is a number having an average value from 0 to 12, .circle.A denotes saturation or aromatic unsaturation in an associated carbocyclic ring and the or each of the R.sup.1 and R.sup.2 groups are independently selected from hydrogen and C.sub.1-12 alkyl groups provided that each --C(R.sup.1)(R.sup.2)-- group contains not more than 13 carbon atoms; and salts thereof; a process for their preparation and curable compositions containing them.
