Abstract

PURPOSE: To prepare a low crystalline soft polymer having excellent transparency and free of surface stickiness, by the random copolymerization of 1-butene and propylene in the presence of a catalyst containing a composite comprising Mg, Ti and a halogen.
CONSTITUTION: To prepare a 1-butene/propylene copolymer having (A) the content insoluble to boiling n-hexane of ≤5.0 wt%, (B) content soluble to boiling methyl acetate of ≤2.0 wt%, (C) a melting point of 40W120°C, (D) an intrinsic viscosity of 0.5W6.0 dl/g. (E) elongation at break of ≥400%, (F) tensile strength of ≥100 kg/cm2, and (G) torsional rigidity of ≤1000 kg/cm2, by the random copolymerization of 1-butene and propylene in the presence of a catalyst composed of (a) a composite containing Mg, Ti and a halogen, (b) an organometallic compound containing a metal of the I-III group of the periodic table, and (c) an electron donor.
