ABSTRACT:
A process for producing novel water-soluble compounds of the formula (HO).sub.m --A--(OCH.sub.2 NR.sup.1 COR).sub.p comprises forming a dispersion of an aqueous solution of a substrate A(OH).sub.n which is an alcohol or, preferably, a carbohydrate and a derivatising reagent HOCH.sub.2 NR.sup.1 COR.sup.2 in a water immiscible liquid and azeotroping the dispersion to remove water and thereby to drive the condensation reaction. The process can achieve high degrees of substitution and is of particular use in the production of water-soluble unsaturated polymersable products, preferably methylol acrylamide derivatives, in a process in which the aqueous dispersed phase contains a water-soluble polymerisation inhibitor. The unsaturated products may be used as cross-linking monomers in many aqueous polymerisation reactions, for instance an aqueous composition containing them with a water-soluble photo-initiator system including a dye are used as curing inks.
