Flow Deformation

Elongation deformation was conducted on a polystyrene-block-polyisoprene-block-polystyrene (SIS) triblock copolymer which contains cylindrical microdomains composed of polystyrene block chains in matrix of polyisoprene block chains. The extensional flow behavior of this deformation triblock copolymer melt, which exhibits a cylindrical phase, has been examined by using elongational deformation with εo between 0.1 and 1.0 s−1 at different temperatures. The structures related to various condition of elongational flow deformation has been determined from SAXS patterns by considering separately changes in the single particle scattering, which influence the scattering patterns. The TEM and SAXS data of the samples show that the cylindrical PS-domain was deformed along the direction of elongation. It also shows that the cylindrical microdomains are micronecked and deformed with various strain rates.
