INTERACTION BETWEEN ISOTACTIC POLYPROPYLENE AND ITS NON-SOLVENTS

Received Date: 8 May 1995

Polypropylene (PP) microporous film prepared by biaxial stretching of isotactic PPis treated with non-solvent liquid at room temperature. The dimension of the film maychange after the treatment. The degree of area contraction of PP film is dependent on thematch between PP and liquid in solubility parameter and polarity. The fact indicates thatsome interactions do exist between liquid and isotactic PP, and a shrinkable porous film isa sensitive probe to detect the weak interactions.
