摘要
Abstract
A central composite design (CCD) mathematic model of response surface methodology (RSM) was adopted to optimize the process parameters of starch-graft-polyacrylamide. The effects of initiator concentration,reaction temperature, and the mass ratio of monomer to starch on the total conversion Y1 and the percentage of grafting Y2 were investigated. The optimum conditions were obtained by contour superposition graph method,including initiator concentration 3.451 mmol/L, reaction temperature 50 ℃, and the mass ratio of monomer to starch 1.54: 1. Under these conditions, the values of Y1 and Y2 are 93.06％ and 54.42％, respectively. The experimental and predicted values of the total conversion and the percentage of grafting are in good agreement.关键词
