“…The viscosities of solutions of polymethyl‐methacrylate (PMMA) in dimethyl formamide have been reported by Shakhovskaya et al10 over a range of temperatures. Tager et al11, 12 found that the viscosity of PMMA solutions in toluene (a good solvent) is lower than that in dihexyl oxalate (a poor solvent). Dreval' et al13 have observed the variation of the viscosity of PMMA in various solvents using the concept of free volume.…”

A Haake 1 viscometer with the NV cupand-bob sensor is used to measure the viscosity, h, of polymethyl methacrylate (PMMA) solutions in methyl methacrylate (MMA) at several polymer concentrations, weight-average molecular weights, and temperatures, and under nonreacting conditions. Six polymer samples having different average molecular weights are prepared by polymerizing MMA in a 1-L batch reactor using 2,2 0 -azoisobutyronitrile (AIBN) as the initiator. Our earlier experimental data (at moderate concentrations of the polymer) on the viscosity of PMMA solutions in MMA under reacting conditions is also used. Two general correlations are developed between h h sol and C poly M 0:76 w with the parameters obtained using genetic algorithm. The tuned correlations for viscosity can be used over an extended range of monomer conversions for model-based state estimation and on-line optimal control of the bulk polymerization of MMA.

“…Several studies have been carried out on the basis of frequency dependent to understand the rheological behavior. [13][14][15][16][17] However, according to our best knowledge, very limited work was reported in the open literature 18 on the rheological properties of the polymer nanocomposites with the variation in temperature. The frequency-dependent analysis usually provides complex viscosity, storage, and loss moduli data, which are useful to ascertain the processing conditions.…”
