Poly cellulose acetate/PMMA

Their applications of machining the microfluidic channels in polymers include a number of substrates poly(ethylene terephthalate) (PET), polystyrene, polycarbonate, cellulose acetate, poly(methyl methacrylate) (PMMA), poly (vinyl chloride) (PVC), poly(ethylene... [Pg.1589]

Hydrophilic polymeric materials, e.g. cellophane and cuprophane, which are both regenerated celluloses have been used for aqueous applications. Other hydrophilic materials used include cellulose acetate (CA) or saponified cellulose acetate, poly(vinyl alcohol) (PVA), polyacrylic acid (PAA), polymethylmethacrylate(PMMA), copolymers of ethylene and vinyl acetate (EVA) or ethylene and vinyl alcohol (EVAL), of polycarbonate and polyether, and more hydrophobic materials such as polycarbonates (PC). [Pg.360]

Sorption equilibria. Equilibrium solubilities of CO2 in a variety of different polymers at 25 C have been determined by our gravimetric desexption method. At higher pressures, the solubilities are quite substantial and vary markedly with the polymer type. Equilibrium uptakes of liquid 0X 2 range from about 3 g/100 g in polyethylene to over 50 g/lOOg in poly(vinyl acetate) other high values have been found for PMMA (27 g/100), ethyl cellulose (30 g/100), and cellulose acetate (27 g/100). [Pg.213]

Figure 12.32 Plot of brittle stress at about — 180 °C against a line joining yield-stress values at —20 °C (o), respectively, for various polymers. Line A divides polymers that are brittle unnotched from those that are ductile unnotched but brittle notched, and line B divides polymers that are brittle notched but ductile unnotched from those that are ductile even when notched. PMMA, poly(methyl methacrylate) PVC, poly(vinyl chloride) PS, polystyrene PET, poly(ethylene terephthalate) SAN, copolymer of styrene and acrylonitrile CA, cellulose acetate PP, polypropylene N, nylon 6 6 LDPE, low-density polyethylene POM, polyoxy-methylene PB, polybutene-1 PC, polycarbonate PTFE, polytetrafluoroethylene.

The interaction parameters suggested by Sun et al. [38] were obtained using viscosity data to determine the miscibility. The ultrasonic velocity of the blend solutions as a function of PVP content is shown in Figure 8.4. For PS/PVP blends, there was an almost insignificant effect of the blend ratio on ultrasonic velocity, which indicated the presence of only one phase. In contrast, the PMMA/PVP blends showed a nonlinearity that indicated the presence of two phases. In the case of the blend system of cellulose acetate/PMMA [39], the nonlinear behavior of ultrasonic velocity with blend composition was due to the blend s immiscible nature. Singh and Singh [40] also attributed the linear variation of the ultrasonic velocity of PMMA/poly(vinyl acetate) with blend composition to the miscible nature of the blend. Singh et al. [41] noted that both the ultrasonic velocity and density with blend composition were linear for miscible blends but nonlinear (S-shaped) for immiscible blends, respectively. [Pg.271]
