The present invention relates to substantially free-flowing polymer particles. The polymer particles are those which have a one millimeter penetration temperature of less than about 75 ~C as determined by thermal mechanical analysis or an unconfined yield strength of greater than about 15 pounds per square foot (73 kilograms per square meter). The composition also comprises an effective amount of an anti-blocking agent in the presence or absence of a binding agent.
L'invention concerne des particules polymères sensiblement fluides. Ces particules sont caractérisées en ce qu'elles possèdent une température de pénétration d'un millimètre, inférieure à environ 75 ·C, telle que déterminée par analyse mécanique thermique, ou en ce qu'elles possèdent une limite d'élasticité non confinée supérieure à environ 15 livres par pied carré (73 kilogrammes par mètre carré). Cette composition comprend également une quantité efficace d'un agent anti-adhérent, un agent de liaison étant éventuellement présent.
