止することができなかった。Molecularly oriented molded products such as fibers and tapes made of ultra-high molecular weight polyolefins have high tensile strength and high tensile modulus, so they are used in applications that require particularly high quality. It may be used for long periods under atmospheric conditions. However, since molecularly oriented molded products made of ultra-high molecular weight polyolefins are essentially polyolefins, they easily deteriorate at high temperatures and have problems with long-term heat resistance stability, such as reduced tensile strength and tensile modulus. Ta. As a method for preventing such thermal deterioration of the ultra-high molecular weight polyolefin molecularly oriented molded article, there is a method of adding a heat-resistant stabilizer to the ultra-high molecular weight polyolefin. However, since ultra-high molecular weight polyolefin molecular alignment products are manufactured through a process in which the diluent is eluted using a solvent such as decalin as a heating medium during stretching of the ultra-high molecular weight polyolefin, ordinary heat-resistant stabilizers cannot be used together with the diluent. Since this stabilizer was eluted into the solvent, thermal deterioration of the ultra-high molecular weight polyolefin molecularly oriented molded article could not be sufficiently prevented.

The intrinsic viscosity [η] measured in °C decalin solvent is at least 5 dff/g, preferably from 5 to 40 dD/g. If the intrinsic viscosity [η] is less than 5 dfl/g, the resulting molecularly oriented molded product will not have sufficient tensile strength, while if it exceeds 40 dj7/g, it will tend to be difficult to mold the molecularly oriented molded product.
