Process for the preparation of substrates for optical disk |
| abstract |
A process for the preparation of substrate for optical disk characterized in that pellets of n 4-methyl-1-pentene polymer or copolymer having a melt flow rate (MFR), as measured according to ASTM D1238 under a load of 5 kg and at a temperature of 260°C, of 240-1200 g/10 min, and a melting point as measured by means of DSC of 234-240°C, nare injection molded into the substrate under the conditions where a temperature of at least part of a cylinder is 320-370°C and a mold temperature is not more than 55°C. |
