| description | Butene-based elastomers were prepared by bulk polymerization of butene-1 and he-xene-1 using self-made supported titanium catalyst, and the optimization of polymerization process was studied. The structure of the copolymers was characterized by nuclear magnetic resonance spectrometer and differential scanning calorimetry, and the physical and mechanical properties of the copolymers were investigated. The results showed that the optimum polymerization conditions were as follow：n(monomers)/n(catalyst) was in range of 20 000 to 25 000, n(triethylaluminum)/n(supported titanium catalyst) was in range of 250 to 300, reaction tem-perature was 45 ℃, reaction time was 4 h，hydrogen pressure was in range of 0.10 to 0.15 MPa. The copolymer contained a random copolymer structure of butene-1 and hexene-1. The copolymer had no fixed melting point. The tensile strength and elastic modulus of the copolymer decreased with the increase of the amount of hexene-1, and the nominal fracture strain of the copolymer reached 534% when the mass fraction of hexene-1 was 20%.
