CA 2337943

In a process for producing thermoplastic resin granules, first a powdery raw material of a thermoplastic resin, which is obtained by polymerizing a plurality of materials and then drying the obtained polymer, is compression-molded by being passed between two rolls arranged parallel with a minute gap therebetween at a temperature of 40 °C or higher, and the obtained compression-molded product is crushed into granules having grain diameters of 10 mm or less.

L'invention concerne un procédé de formation de granules d'une résine thermoplastique caractérisé en ce qu'une matière pulvérulente de résine thermoplastique obtenue par polymérisation d'une pluralité de matières premières et séchage du produit obtenu, est soumise à un moulage par compression à une température de 40 DEG C ou supérieure, entre deux rouleaux lesquels sont agencés en parallèle l'un par rapport à l'autre, avec un interstice étroit, et le produit formé et obtenu est broyé pour obtenir des granules ayant un diamètre de 10 mm ou moins.
