Economic production of VAc and VEOVA 10 emulsion polymer using factorial design

Abstract

Emulsion polymerisation of vinyl acetate (VAc) and vinyl ester of versatic acid (VEOVA 10) was carried out using different feed composition ratios. The copolymer emulsion was characterised by measuring the morphological properties (average particle diameter, D) by using the transmission electron microscope (TEM); minimum film forming temperature (MFFT) and filtration residue (ppm). The results of the study indicate that the average particle diameter of emulsion (D) decreases with the increase of the amount of VEOVA 10 content (and subsequently decreases the amount of VAc), also the ppm and the MFFT is decreased. These results were illustrated using response surface methodology and contour plots. In this paper, the economic production of VAc and VEOVA 10 emulsion polymer was studied to ensure the best performance of all properties at minimum cost utilising multiobjective optimisation methodology.Keywords: emulsion polymerisation; vinyl acetate; VAc; vinyl ester of versatic acid; VEOVA 10; factorial design; response surface methodology; design expert software. 90 I.

“…After the reaction was continued, a calculated concentration of 2.2-Azobisisobutyronitrile was separately added to the reactor along 30min, then the reaction was continued for another 1 hr. At the end, the latex was cooled down to room temperature [19][20].…”
