We demonstrate a versatile method to encapsulate calcium carbonate particles with a shell of polymer by means of a conventional free radical emulsion polymerization process. Our strategy relies on the encapsulation of the pigment particles with a thin primer layer of crosslinked poly(acrylate). Starved-fed addition and emulsion polymerization of di(ethylene glycol) diacrylate and methacrylic acid allow the uniform decoration of the pigment particles with the polymer primer shell. We demonstrate efficient encapsulation of calcium carbonate, from which we produce hollow particles upon calcium carbonate etching. The thickness of the polymer shell can easily be controlled, which we demonstrate with sequential seeded polymerization of Me methacrylate under starved-fed conditions. In the experiment, the researchers used many compounds, for example, Diethyleneglycoldiacrylate (cas: 4074-88-8Recommanded Product: 4074-88-8).
Diethyleneglycoldiacrylate (cas: 4074-88-8) belongs to alcohols. A strong base can deprotonate an alcohol to yield an alkoxide ion (R―O−). For example, sodamide (NaNH2), a very strong base, abstracts the hydrogen atom of an alcohol. Tertiary alcohols cannot be oxidized at all without breaking carbon-carbon bonds, whereas primary alcohols can be oxidized to aldehydes or further oxidized to carboxylic acids.Recommanded Product: 4074-88-8
