丁基橡胶三维溶度参数的测定及应用
采用溶胀法和计算机HSPiP软件模拟测定了丁基橡胶（IIR）的三维溶度参数,并研究了三维溶度参数在确定相对能量差（RED）与溶胀比（q）的关系及建立Teas二维溶度参数图中的应用.结果表明,IIR的三维溶度参数δd、δp、δh分别为17.1,1.2,0.7 MPa1/2,根据Hansen模型计算得出IIR的一维溶度参数为17.16 MPa1/2,与溶胀法测试结果基本一致;IIR的q值随着RED的增大而减小,并在RED为1时出现拐点,此时溶剂由良溶剂转变为不良溶剂;在Teas二维溶度参数图中,位于IIR溶解区域内的溶剂为良溶剂,溶解区域外的为不良溶剂....

| Bibliography: | swelling method;ber; three-dimensional solubilitydifference ; swelling ratioHSPiP software; butyl rub-parameter; relative energy The three-dimensional solubility parameters of butyl rubber （IIR） were determined by swelling method and HSPiP software simulation calculation, and the obtained three-dimensional solubility parameters were applied to deter- mination of relationship between relative energy difference （RED） and swelling ratio（q） and the establishment of Teas two-dimensional graph. The results showed that the three-di- mensional solubility parameters δd , δp, δh of IIR were 17. 1, 1.2, 0.7 MPa^1/2 respectively, the one-dimensional solubility parameter calculated by Hansen model was 17.16 MPa^1/2,which was consistent with that determined by swelling meth- od. With increasing RED, q value decreased and inflection appeared in the plot of q versus RED when the RED was 1, at which point, the solvents changed from good to poor. In Teas two-dimensional graph of IIR, the solvents in the soluble re- gion were go |
