Granules and pellets for the modification of polycondensates which can be shaped, as well as the process for obtaining these granules and pellets and shaped articles thus obtained

Process for obtaining granules and pellets characterised in that it comprises:

• a. the densification of a mixture containing:
• at least 37.5% of polycondensates serving as a carrier, of which at least a part consists of the same polycondensate as that which is to be shaped, in the form of a powder of particle size at least 50 microns,
• from 12.5 to 40% of a binder of melting point 70.degree.-100.degree. C which is compatible with the polymer to be shaped and,
• up to 50% of at least one compound intended to modify the polycondensate to be shaped, by means of a turbo-mixer, the temperature at the end of the operation being above the melting point of the binder, and
• b. the forming of granules or pellets from said mixture by means of a compacter or pelletiser, at a temperature at least equal to the melting point of the binder, the densified mixture being introduced at a temperature of at least about 50.degree. C.
