Abstract
Since Carbon Dioxide(CO2) is a good solvent for most liquid vinyl monomers and a poor solvent for most polymers, it has been used as a medium dispersion polymerization. It has unique characteristics such as high diffusivity, liquid-like density, zero surface tension, low viscosity, high fast mass transfer and tunable solvent power. In addition, it is inexpensive, recyclable, non-flammable and non-toxic. It also has advantage of easy separation from products and resolves problems related to solvent removal.
In this paper, we report the dispersion polymerization of MMA using poly(dihydroperfluorooctyl methacrylate-co-dimethylaminoethyl meth acrylate)(p(FOMA-co-DMAEMA)), poly(2,2,3,3,4,4,4-heptafluorobutyl methacrylate-co-diisopropylaminoethyl methacrylate) (p(FBMA-co- DPAEMA)), poly(2,2,3,3,4,4,5,5-octafluoropentyl methacrylate -co-diisopr opy laminoethyl methacrylate)(p(FPMA-co-DPAEMA)) and poly(3- [tris(trimethylsilyloxy)silyl]propyl methacrylate-co-dimethylaminoethyl methacrylate)(p(SiMA-co-DMAEMA)) copolymers synthesized in this study as a stabilizer in scCO2. The effects of varying the concentrations of stabilizer and monomer, reaction pressure upon the polymerization yield, molar mass and morphology of the resulting Polymethylmethacrylate(PMMA) have been explored.
