Zusammenfassung:	The present invention relates to a composition comprising a) an aqueous dispersion of styrenic copolymer particles having a z-average particle size in the range of from 50 to 500 nm; and b) a C4-C10-alkyl hydroperoxide having a concentration in the range of from 250 ppm to 5000 ppm, based on the weight of the composition. The composition of the present invention provides a latex that is resistant to microbial growth even in the absence of a biocide. La présente invention concerne une composition comprenant a) une dispersion aqueuse de particules de copolymère styrénique ayant une taille de particule moyenne z dans la plage allant de 50 à 500 nm ; et b) un hydroperoxyde d'alkyle en C4 à C10 ayant une concentration dans la plage comprise entre 250 ppm et 5000 ppm, sur la base du poids de la composition. La composition de la présente invention fournit un latex qui est résistant à la prolifération microbienne même en l'absence d'un biocide.
