| Abstract: | When polypropylene is compounded with 0.01%-0.1% 4-hydroxy 2,2, 6, 6-tetra-methyl-piperidine-1-oxyl, the rheological properties of the melt of polypropylene are modified, so that the temperature of spinning can be lowered from 330℃ to 280℃ and the fiber obtained has a tenacity of 5g/d. |
