| Abstract: | The method of solubility parameter including group contribution calculation method of three dimensional solubility parameter,IGC and DSC was used to study miscibility of polymer PC and PCCD.The effect of dispersion,polar and hydrogen bonding interactions between molecules on the miscibility of PC and PCCD were considered.The three dimensional solubility parameters were calculated by using group contribution method,solubility parameters of each dimension(dispersion,polar and hydrogen bonding) were very close.IGC showed δPC=18.1(J/cm3)1/2,δPCCD=17.3(J/cm3)1/2.The two parameters were very close.DSC showed PC and PCCD blends had only a Tg,and between PC′s Tg and PCCD′s Tg.The three method including group contribution method,IGC and DSC demonstrated that PC and PCCD were compatible. |
