ΕΙΣΑΓΩΓΗ ΚΑΙ ΜΕΛΕΤΗ ΜΙΑΣ ΝΕΑΣ ΚΡΙΣΙΜΗΣ ΣΥΓΚΕΝΤΡΩΣΗΣ ΣΤΗ ΠΕΡΙΟΧΗ ΤΩΝ ΑΡΑΙΩΝ ΜΑΚΡΟΜΟΡΙΑΚΩΝ ΔΙΑΛΥΜΑΤΩΝ

A VISCOMETRIC STUDY OF TERNARY SYSTEMS POLYMER A - POLYMER B - SOLVENT, WE DETERMINED A NEW CRITICAL CONCETRATION C** WHICH SEPERATE THE DILUTE SOLUTIONS IN TOW REGIMES. THE REGIME OF VERY DILUTE SOLUTIONS C C<C** AND THE REGIME OF DILUTE SOLUTION (C>C**). IT IS PROPOSED A MODEL WHICH DESCRIBE THIS CRITICAL CONCENTRATION. THE INFLUENCES IN THIS CRITICAL CONCENTRATION OF THE SOLVENT, THE TEMPERATURE AND THE PRESENCE OF A COPOLYMER WERE STUDIED. USING VISCOMETRIC METHOD IT IS ALSO DETERMINED AND THE CRITICAL CONCENTRATION C*, WHICH SEPARATES DILUTE FROM THE SEMI- DILUTE SOLUTIONS, FOR TERNARY SYSTEMS. THE TWO CRITICAL CONCENTRATIONS C**, C* ARE COMPARED. THE INFLUENCES OF THE TEMPERATURE AND OF THE HYDRODYNAMIC VOLUME OF THE POLYMERS ON THE CRITICAL CONCENTRATIONS ARE ALSO PRESENTED.
