| titleOfInvention | Process for the preparation of polymer yarns from ultra high molecular weight homopolymers or copolymers, polymer yarns, molded polymer parts, and the use of polymer yarns |
| abstract | A process for the preparation of polymer yarns from ultra high molecular weight homopolymers or copolymers, wherein the process includes the following steps: n (a1) preparing a suspension of a homopolymer or copolymer and a spinning or gelling solvent, of a non polar nature at a weight of homopolymer or copolymer to solvent ratio from 2/98 to 30/70; wherein said homopolymer or copolymer has a monomodal, bimodal or multimodal molecular weight distribution, and is obtained from C 2+n monomers, wherein n varies from 0 to 2;n (b1) feeding said homopolymer or copolymer suspension, to an extruder; (c1) extruding the suspension with the formation of a gel, at a temperature in excess of 150° C., under regular atmospheric or inert conditions; (d1) spinning the gel to obtain non-stretched filaments with diameters of at least 1 mm, at a temperature in excess of 150° C., while maintaining regular atmospheric or inert conditions; (e1) cooling the non-stretched filaments or yarns; (f1) taking up the non stretched filaments or yarns, at a velocity in excess of 10 m/min; (g1) feeding the non-stretched filaments or yarns, to an extractor together with the feed of an organic extraction solvent, with a boiling point below 80° C.; (h1) extracting said non-polar long chain solvent impregnated in the yarns at a temperature of at least 30° C. and a pressure of at least 196 kPa (2 kgf/cm 2 ); (i1) removing the spent organic solvent from the extractor; (j1) drying the non-stretched filament bundles or yarns wherein the dry yarn has at most 4%, by weight, and preferably at most 2%, by weight, of the non polar long chain solvent; and (h1) stretching said dry yarns at a temperature in excess of 80° C. |
