| Abstract: | The structure and properties of poly(1-butene)(PBt)in the presence of supported titanium and Al(i-Bu)3 were investigated.The results of dissolution test spectra of 13C-NMR showed that the PBt include both isotactic(i-)and atactic(a-)structure.Isotactic content was about 67% and the melting point of i-PBt was 97 .Mechanical properties of the PBt were that tensile strength 9.7 MPa,elongation at break 490%,Shore A hardness 87,permanent set 82%.The PBt belonged to thermoplastic elastomer. |
