“…Th e water uptake dependence on the copolymer structure gave information on the hydrophilicity of these copolymers. Crosslinked copolymers of AA and EA and some ion exchangers derived from them containing either primary amine groups or carboxylic groups were studied by Dragan et al [136], where DVB and MBAA were used as crosslinkers. Th e copolymers and the corresponding ion exchangers were characterized by IR spectroscopy, swelling behavior and thermogravimetric analysis.…”

Acrylic copolymers have achieved prime importance in various avenues of industrial application such as adhesive in packaging and construction, binder and stabilizer in textiles, base coat in leather, topcoat in fl oor polish, pigment binder in paper industries, etc. Acrylic resins are generally known to have superior exterior durability and weather resistance compared to other organic binders/fi lm-formers commonly used in surface coatings. Th e emulsion polymerization of acrylic monomers provides a good combination of performance properties required in fi lm formation. Th ese properties depend on the copolymer composition, particle size, molecular weight, glass transition temperature (Tg), morphology of the latex particles, etc.In this chapter, the reaction components and polymerization process conditions that aff ect the inherent characteristics of the polymers are presented. Th ere is a discussion of the incorporation of comonomer, which would lead to an improvement in the fl exibility of fi lms produced along with adhesion, gloss, hardness, solvent resistance, water resistance, etc. Also, there is a recently developed successful approach for achieving balanced properties which involves the copolymerization of fi lm-forming monomers like acrylate and methacrylates with crosslinkable monomers.

“…They determined the degree of crosslinking by γ -irradiation, extraction and swelling experiments. Vlad and co-workers [8] correlated the synthesis conditions of the acrylamide co-polymers with the properties of the ion exchangers derived from them, using divinylbenzene and N ,N -methylenebis acrylamide as cross-linker. It was observed that the structural changes in acrylamide co-polymers took place on account of the chemical reactions.…”

“…The water uptake in dependence on the co-polymer structure gave information on the hydrophilicity of these co-polymers. Cross-linked co-polymers of acrylamide (AM) and ethylacrylate and some ion exchangers derived from them containing either primary amine groups or carboxylic groups were also studied by Dragan et al [8].

Co-polymers of methyl methacrylates (MMAs) are widely used in coatings because of their film-forming capacity, which is due to better bond-forming tendency with various substrates. The adhesion of coating with various substrates such as wood, metal or plastics is an important property for protective, as well as decorative coatings. Co-polymers of MMA with different monomers such as butyl acrylate (BuA), 2-ethyl hexyl acrylate (2-EHA) and hydroxyl ethyl methacrylate (HEMA) are extensively used for coatings on different substrates to improve the roughness, acid scratch and solvent resistances. Co-polymerization of diacrylates/dimethacrylates of glycols with various alkyl esters have been investigated by several scientists. In the synthesis of these materials an understanding of polymerization mechanism and kinetics is important for better control of gel structure. The rate constant depends largely on the physical properties of the system, which in turn, are strong functions of monomer conversion. Cross-link density is one of them, and T g also depends on it, increasing with increasing cross-link density.

“…Functional copolymers, linear and crosslinked, bearing primary amine groups are of great interest because of their high reactivity, which allows the incorporation of numerous additional moieties. 3 However, ion exchangers with primary amine groups are difficult to obtain by chemical reactions with St-DVB copolymers.…”

Ion-exchange polymers were used successfully in water-treatment operations. In this study, three ion-exchange resins based on 4-vinylpyridine and divinylbenzene functionalized with N-oxide groups were obtained. Their ion-adsorption properties were measured in solutions containing chromium at concentrations of 4 and 500 ppm with column and batch equilibrium techniques. The removal efficiency of the chromium ions with HCl was observed to increase after the protonation of the N-oxide groups. The resins could be reused after 10 cycles with the metal removal efficiency maintained at higher than 95%. These studies evidenced a strong correlation between the morphology and ionic group content in the resin and its chromium ion sorption capability.
