抄録

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.
