The present invention relates to a process for preparing dry polymer granules having increased minimum ignition energy, lowered to unchanged maximum explosion pressure, lowered explosion strength (Kst) coupled with reduced dusting levels by drying a mixture including one or more emulsion polymers and one or more surfactants having HLB values between 10 and 25.
La présente invention a pour objet un procédé de préparation de granules de polymère secs ayant une énergie minimale d'inflammation accrue, une pression maximale d'explosion moindre ou inchangée, une résistance à l'explosion (Kst) moindre couplées à des niveaux de poussière réduits, par séchage d'un mélange comprenant un ou plusieurs polymères en émulsion et un ou plusieurs agents tensio-actifs et ayant un HLB compris entre 10 et 25.
