Process for the production of polyethylene materials. |
| 摘要 |
A process for producing a polyethylene material for use in products requiring high mechanical strength and high elastic modulus is disclosed. The process involves the use of a specific class of particulate polyethylenes having an intrinsic viscosity of 5 - 50 dl/g in decalin at 135 DEG C and the steps of compression-molding, solvent-immersing, solid-phase extruding or rolling and finally drawing the material in that order.
