    摘要： The fine powder of high molecular weight fluorine containing resins having melt viscosities of 106 to 1013 poise, apparent density of 0.4 to 1.5 g/cc, and specific surface area of 2 m2/g or less, mold goods of the fine powder and these production methods. By utilizing the fine powder of high molecular weight flourine containing fused resins that have previously not been employed, the mold goods obtained from the fine powder have fewer liquated particles and have become the most suitable especially for manufacturing semiconductors. The powder's products have greater resistance to flex fatigue, abrasion, resistance, etc.

    摘要： A process for preparing low molecular weight polytetrafluoroethylene having a melting point of 250.degree. C. to 325.degree. C. comprising polymerizing tetrafluoroethylene in at least one polymerization solvent selected from the group consisting of hydrochlorofluorocarbons, hydrofluorocarbons and perfluorocarbons which have boiling points in the range between -10.degree. C. and 70.degree. C. under constant pressure by the supplement of tetrafluoroethylene. According to this process, the low molecular weight polytetrafluoroethylene which is useful as an additive to various materials is produced in the solvent which has a low ozone destruction factor or does not destroy the ozone, under economically advantageous low pressure which can be controlled safely.
