A method of making polymeric particulates (P) wherein polymeric scrap material. virgin polymeric material and mixtures thereof (M) are supplied to intermeshing extruder screws (14) which rotated to transport the polymeric material along their length (SN Total) and subject the polymeric material to solid state shear pulverization and in-situ polymer compatibilization, if two or more incompatible polymers are present. Uniform pulverized particulates are produced without addition of compatibilizing agent. The pulverized particulates are directly melt processable (a powder feedstock) and surprisingly yield a substantially homogenous light color product.

L'invention se rapporte à un procédé de fabrication de particules polymères (P) dans lequel on alimente en matériau de récupération polymère, en matériau polymère vierge ainsi qu'en mélanges de ces matériaux (M), une extrudeuse à vis (14) engrenantes qui tournent afin de transporter le matériau polymère sur toute leur longueur (SN totale), le soumettent à une pulvérisation par séparation de son état solide et rendent les polymères compatibles in situ si au moins deux polymères incompatibles sont présents. Des particules pulvérisées uniformes sont ainsi produites sans l'addition d'un agent de compatibilité. On peut traiter directement par voie fondue ces particules pulvérisées (en tant que charge en poudre) qui donnent alors, de manière étonnante, un produit légèrement coloré et sensiblement homogène.
