“…Literature concerned with the free radical polymerization of acrylic resin has been reported by many workers in the fi eld [5][6][7][8]. Th e relative ease of polymerization and the wide range of properties among the acrylic resins have led to the commercial production of many diff erent resins suitable for a broad variety of applications [9].…”

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.

Free radical solution copolymerization of acrylonitrile (AN) and itaconic acid (IA) was performed with DMSO-d 6 as the solvent and 2,2 0 -azobisisobutyronitrile (AIBN) as the initiator. Weight ratio of the monomers to solvent and molar ratio of initiator to monomers were constant in all experiments. The initial comonomer composition was the only variable in this study. On-line 1 H NMR spectroscopy was applied to follow individual monomer conversion. Mole fraction of AN and IA in the reaction mixture (f) and in the copolymer chain (F) were measured with progress of the copolymerization reaction. Overall monomer conversion versus time and also compositions of monomer mixture and copolymer as a function of overall monomer conversion were calculated from the data of individual monomer conversion versus time. Total rate constant for the copolymerization reaction was calculated by using the overall monomer conversion versus time data and then k p /k t 0.5 was estimated. The dependency of k p /k t 0.5 on IA concentration was studied and it was found that this ratio decreases by increasing the mole fraction of IA in the initial feed. The variation of comonomer and copolymer compositions as a function of overall monomer conversion was calculated theoretically by the terminal model equations and compared with the experimental data. Instantaneous copolymer composition curve showed the formation of alternating copolymer chain during copolymerization reaction.
