The application of response surface methodology on the synthesis of grafted polypropylene through the solvothermal route

Abstract

Solvothermal synthesis is an important technology to prepare the inorganic matter. In this investigation, xylene-water-thermal reaction of polypropylene (PP), styrene (St), and maleic anhydride (MAH) under pressure was carried out to prepare grafting polymers. Infrared (IR) spectra and NMR spectra confirmed that MAH and St were successfully grafted onto the PP backbones. Through differential scanning calorimetry (DSC) and X-ray analysis,

Synthesis of Poly(AAm-<i>co</i>-AA) and Investigation of its Swelling Behavior: Using Response Surface Methodology (RSM)

“…Table 1 shows the mixing ranges of these key factors. As reported in [20], the mole ratio of AAm/AA and the mole percentage of the crosslinker agent in the copolymerization reaction are better to be in the range of 2 -10 mole ratio and 4 -20 mole percentage, respectively. In addition, several authors were used these mentioned ratios for AAm/AA and MBA [16] [30].…”

Mechanochemistry: a novel approach to graft polypropylene with dual monomers (PP-g-(MAH-co-St))

“…However, it is difficult for the copolymerized MAH to homopolymerize. This leads to a decreased trend of MAH grafted onto PP and severe degradation of the PP backbone [6,10,11]. Recently, for the better grafting of MAH onto PP, adding styrene (St) as a second monomer onto PP at the same time not only increases the grafting proportion of MAH onto PP (G MAH ), but also reduces the PP chain scission degradation in near literature [12].…”

“…The grafting technique with reactive monomers onto PP has been widely used in the modification of PP to overcome these problems [3][4][5][6]. Maleic anhydride (MAH) was extensively studied to modify PP in commercial applications due to its unique combination, low cost, high activity, and good processibility [3][4][5][6][7][8][9].…”

Optimization of Polymeric Membrane Characteristics through Thermal Treatment and Deposition of Polyelectrolyte Layers Using Response Surface Modeling

“…[9][10][11][12][13] Previously, membrane modification or fabrication studies normally involved conventional experimentation methods. RSM has been proved to be an effective tool for investigation, modeling, and optimization processes.…”

“…RSM has been proved to be an effective tool for investigation, modeling, and optimization processes. [9][10][11][12][13] Previously, membrane modification or fabrication studies normally involved conventional experimentation methods. In this kind of the conventional method, only one parameter could be varied while maintaining the others constant at various stages.…”
