COMPOSITIONS BASED ON FLUORINATED RESIN AND IMIDE COMPOUND, PREPARATION METHOD AND USES

摘要

The invention concerns compositions based on fluorinated resin having a particularly low swelling of hydrocarbons and organic substances, in particular in extreme temperature and/or pressure conditions. Said compositions are obtainable by a method which consists in mixing 100 parts by weight of at least one fluorinated polymer and 1 to 70 parts by weight of at least one compound bearing functional maleimide and/or nadimide groups, the fluorinated resin(s) being in melted state during the mixing step. Said compositions can be used for transporting and/or storing hydrocarbons and natural gas, and also in chemical engineering and the building industry.
