A. Danait et Dd. Deshpande, A NOVEL METHOD FOR DETERMINATION OF POLYMER-POLYMER MISCIBILITY BY VISCOMETRY, European Polymer Journal, 31(12), 1995, pp. 1221-1225
A method based on the intrinsic viscosities of transfer of polymers in
pure and ''mixed'' solvents has been proposed to study the miscibilit
y of polymer blends. Using this approach, blends of polystyrene with p
olyvinyl chloride, polyvinyl acetate and vinyl chloride-vinyl acetate
copolymer have been found to be immiscible. Also blends of polyvinyl c
hloride with poly(n-butyl methacrylate) are found to be miscible. Conc
lusive support has been obtained from thermal analyses studies of the
blend films. Chee's method has been found to give unreliable results f
or the blends studied.
