ABSTRACTHigh molecular weight water-soluble polymers are usually supplied in the form of water-in-oil emulsions which have advantages of low viscosity and easy storage and dissolution. Most uses in water treatment, flocculation, paper manufacture or mining fields require polymer latexes formed of finely dipersed particles. Polymerization in reverse micelles or microemulsions appears to be an attractive technique because it can lead, under appropriate formulations, to high molecular weight polymers entrapped within small-sized stable particles. The main characteristics and properties of the latexes and polymers formed by this process are described.

Viscosity modifying admixtures (VMA), known as an important component, are water-soluble polymers that can increase the viscosity and cohesion of self-compacting concrete( SCC). This article presents the effect of four different types of VMA on the workability of SCC , which including flowability, filling ability, passing ability and segregation resistance ability of the fresh concrete. The results show that the low viscosity of VMA satisfies the workability requirement of fresh properties of SCC.

AbstractA method is described for the preparation β-glycosylamide monomers from reducing carbohydrates. The glycosylamide monomers were copolymerized with acrylamide to formhigh molecular weight, water soluble polymers. The chemical and enzymatic stability of the β-N-glycosidic linkage was investigated. In addition, the glycopolymers were characterized by their interactions with lectins.
