Complex Formation between Polymers and Complexing Agents

3 Complex Formation between Polymers and Complexing Agents 

Interactions between polyvinyl chloride (PVC) and cyclohexanone or n-methyl-2-pyrrolidone generated the occurrence of local configurational changes. The results suggest that the interaction is restricted to a definite number of polymer sites although no information as to the exact type of these sites can be drawn. The number of interaction sites is higher for cyclohexanone than for A -methyl-2-pyrrolidone (181).
