Abstract
Process for the manufacture of polyethylene objects and orthopedic auxiliary means, characterized in that polyolefins are applied, in particular, polyethylene with visco-symmetrically determined molecular weights of more than 100,000, preferably of 1,000,000 approx. The latter are obtained by polymerization of olefins at pressures of less than 100 kilos/cmº. Approx. And at temperatures up to 100º with the application of catalysts, consisting of mixtures of metal-organic combinations, especially aluminum-alkyne combinations, with combinations of metals of the secondary group 4º to 6º of the periodic system, especially with titanic combinations, for example, titanium halides.
