Abstract

Highly sulphonated MELAMINE-FORMALDEHYDE RESIN (HSMF) is prepared by atmospheric reflux from melamine, formaldehyde, sodium sulphite and metabisulphite through-a four-step reaction. The sulphite/melamine molar ratio between 1.0-2.0 and the formaldehyde/melamine molar ratio varied between 3.0 and 5.0. The effects of degree of sulphonation and F/M ratio on the fluidity of resin solutions were studied. The F/M ratio is directly and S/M ratio is inversely proportional to viscosity of the resin solution. Because of lower viscosity of HSMF resins than that of SMF resins, it is expected to be more effective SUPERPLASTICIZER in cement sand mortar. The results show that viscosity of the solutions increases with increasing MW of the polymers until a critical molecular weight, beyond which there is a rapid increase in viscosity due to formation of a hexagonal close-packed system.
