Abstract
Procédé de fabrication d'une composition de moulage thermodurcissable granulaire contenant de la résine phenolique novolaque ayant des caractéristiques de surface modifiées. La composition est caractérisée par la mise en forme de la composition de moulage en granules de 2 à 9 mm et par le mélange de ces granules avec une quantité de 0,7 à 2,5 % en poids par rapport au poids des granules, d'un mélange d'acétone et d'au moins un polymère d'esters alkyles, des acides acryliques et méthacryliques ayant de 1 à 5 atomes de carbone dans le radical alkyle ces polymères étant présents dans le mélange en quantités allant de 1 à 20 % en poids. Application au moulage des matières plastiques.
