Siloxane, dimethyl-, copolymer with stabilization

In addition to polymer latexes, inorganic suspensions may also be formed in CO2. (10) Block copolymers have been shown by turbidimetry to stabilize 1 pm hydrophilic silica dispersions in CO2, with stability decreasing in the order PS-Z)-PFOA > poly(methyl methacrylate-co-hydroxyethyl methacrylate)-g-PFPE > poly(dimethyl-siloxane)-g-pyrrolidone carboxylic acid (PDMS-g-PCA) (MW 8500 g/mol, 2 PCA groups). The decrease in stability with decreasing CO2 density was sharper for higher molecular weight C02-philic segments, as expected based on the nature of polymer chain collapse. [Pg.239]
