Methyl methacrylate-dimethylsiloxane block copolymers

Well-defined poly(dimethylsiloxane)-block-poly (methyl methacrylate)-block-poly(2,2,3,3,4,4,4-heptafluorobutyl methacrylate) (PDMS-( -PMMA-( -PHFBMA) triblock copolymers were synthesized by Lian et al. via ATRP, and their microstructures were investigated using atomic force microscopy (AFM) [56]. 

Dawkins and Taylor109 dispersed poly(methyl methacrylate) (PMMA) or polystyrene (PS) particles in n-alkanes stabilized by AB block copolymers of styrene and dimethyl-siloxane. In these cases, styrene blocks act as anchors and dimethylsiloxane blocks give a surface layer. The thickness 6 of the dimethylsiloxane layer was determined by viscosity measurements as a function of the molecular weight of dimethylsiloxane blocks.
