Determination of Three-dimensional Solubility Parameter of CIIR Based on Hansen Theory

基于Hansen理论测定氯化丁基橡胶(CIIR)的三维溶解度参数,并提出判定CIIR与溶剂相容性的方法。结果表明:采用平衡溶胀法测定CIIR139在不同溶剂中的溶胀比,通过HSP软件计算得出CIIR139三维溶解度参数为17.22 MPa1/2;可以橡胶与溶剂在三维空间图中的距离表示二者相互作用力和相容性;通过HSP软件模拟CIIR139与溶剂在三维空间和投影面中的相对位置,可以判定溶剂是否为良溶剂。

Based on Hansen theory,the three-dimensional solubility parameters of chlorinated butyl rubber(CIIR)were determined,and the method to determine the compatibility between CIIR and solvent was proposed.The equilibrium swelling method was used to determine the swelling ratio of CIIR139 in different solvents,and the three-dimensional solubility parameter of CIIR139 was 17.22 calculated by HSP software.The distance between rubber and solvent in the three-dimensional space map could indicate the mutual force and compatibility.The relative position of CIIR139 and solvent in the three-dimensional space and projection plane could be determined by HSP software simulation,which could determine whether the solvent was good or not.
