Inhibitors such as MEHQ (monomethyl ether hydroquinone) and PTZ (phenothiazine) are added to acrylic acid in the shipping and storage process to prevent its spontaneous polymerization. Dissolved oxygen is also an strong inhibitor, and its presence in

Attenuated Total Reflection (ATR) UV spectroscopy has been used to monitor monomer conversion in methyl methacrylate miniemulsion polymerization. It was found that the vinylic groups of methyl methacrylate strongly absorb the UV light with a maximum

In water-based polymerization (suspension, microsuspension, emulsion, miniemulsion, and microemulsion polymerization), the solubility of the monomer in the aqueous phase can have profound effects on the final polymer product. This article demonstrate

The miniemulsion and macroemulsion polymerization of vinyl acetate with vinyl versatate in batch and semibatch systems was investigated. Vinyl versatate was added either as an emulsion with the vinyl acetate, or as a neat liquid stream. In the batch

The kinetics of miniemulsion polymerization of vinyl acetate, in which nonionic surfactant, Brij-35 [polyoxyethylene(23) lauryl ether], and hexadecane were used, was investigated. For comparison, experiments were also carried out using an anionic sur

Three monomer systems, vinyl acetate/butyl acrylate [VAc/BA], vinyl acetate/dioctyl maleate [VAc/DOM] and vinyl acetate/n-methylol acrylamide [VAc/NMA], with large differences in reactivity ratios and water solubilities were selected to carry out the

As part of a wider effort to develop a new class of waterborne coatings, hybrid miniemulsion polymerization was carried out with acrylic monomers (methyl methacrylate, butyl acrylate, and acrylic acid) in the presence of oil-modified polyurethane res

Continuous miniemulsion polymerization has been carried out in a single CSTR with both hexadecane (HD) and a polymer as the hydrophobe. Conventional emulsion (macroemulsion) polymerizations using similar recipes exhibit the oscillatory behavior chara

In aqueous emulsion and miniemulsion polymerization, the product may be dependent upon the ability of the monomer(s) to diffuse across the continuous aqueous phase. This, in turn, is dependent upon the solubility of the monomer in the aqueous phase.
