- Studies on Rheological Behavior of Polyvinyl Alcohol Fiber (PVA Fiber) Grafted with Styrene
説明
The PVA fiber grafted with styrene were prepared by the emulsion method using potassium persulfate (KPS) as the catalyst.<BR>The viscoelastic properties of these fibers were investigated as a function of degree of grafting. The results are as follows.<BR>1) Viscoelasticities, glass transition temperatures and thermograms of differential thermal analysis showed that the two components (PVA and polystyrene) seem to exist in two seperated phases.<BR>2) The modulus of the copolymer with high degree of grafting was represented by a simple parallel mechanical model, that is, the complex modulus E* of this system was described by the equation of E*=λEPS+(1-λ)EPVA*, where λ is the volume fraction of polystyrene, Eps* and EPVA* are the complex moduli of polystyrene and PVA fibers, respectively.<BR>3) These graft copolymers behaved almost in the same way as the mechanically blended system which was composed of the corresponding two components.
