| Abstract: | According to the effect of viscosity increasement by solid-phase polymerization of different lustrous chips under the same condition, the quality of the above chips was analyzed. The factors having effect on viscosity increasement were discussed. The speed of viscosity increasement and intrinsic viscosity of the chips was improved by increasing crystal temperature, crystal time and reaction temperature of after polymerization. |
