Abstract
Process for the manufacture of materials applicable in the construction of objects that have to withstand extraordinarily low temperatures below 150º C below zero to below 260 below zero (up to about 125º Kelvin), characterized in that said polyolefin materials or polyolefin blends are manufactured , especially of polyethylene, with a molecular weight, determined viscosimetrically, from 500,000 to approximately 1,000,000 more than for its part were produced by polymerization at pressures up to 100 atmospheres and temperatures up to approximately 100º in the presence of catalysts of aluminum alkyl combinations and combinations of metals of the 4th - 6th secondary group of the periodic system, preferably of titanic combinations.
