Easily soluble polyethylene powder for the preparation of fibers or films having high strength and high elastic modulus |
| abstract |
ABSTRACT An ultra-high molecular weight polyethylene powder easily soluble in organic solvents and suitable for use in the preparation of fibers or films having a high strength and a high elastic modulus, said polyethylene powder having an intrinsic viscosity in the range of 5 to 30 dl/g in decalin at 135°C and being obtained by at least two-step polymerization reactions which are: a first step of polymerizing ethylene in the absence of hydrogen or at a reduced hydrogen concentra-tion, using a catalyst containing a solid catalyst component and an organometallic compound, said solid catalyst component containing at least magnesium and titanium and/or vanadium, to produce 50-99.5 parts by weight, based on 100 parts by weight of a final polyethylene product, of polyethylene having an intrinsic viscosity of 12 to 32 dl/g in decalin at 135°C, and a second step of polymerizing ethylene at a higher hydrogen concentration than in said first step to produce 50-0.5 parts by weight of polyethylene. |
