The effect of introduced hydrogen bonding on miscibility of polymer blends studied by excimer fluorescence

Summary

Polymer-polymer miscibility in immmiscible polymer blends can be considerably enhanced by introducing specific interactions between component polymers. In this paper, the effect of, introduced hydrogen bonding in blends of modified polystyrene containing hydroxyl groups and copolymer of 2-vinyl naphthalene and methyl methacrylate is examined by excimer fluorescence. This technique is proved to be effective in monitoring the degree of mixing of the component polymer chains as functions of both intensity of hydrogen bonding and concentration of the guest polymer. The results also indicate the presence of heterogeneity of chain distribution on a very small scale which may be undetectable by routine techniques.
