Beschreibung
Zusammenfassung:	The invention pertains to an aramid particle containing a peroxide radical initiator wherein the particle contains 3-40 wt% peroxide radical initiator based on the weight of the aramid particle. The invention also relates to a particle-elastomer composition comprising: (a) 100 parts by weight of at least one natural or synthetic elastomer, particularly rubber; (b1) 0.1 to 25 parts by weight of sulfur, an amount of a sulfur donor providing the equivalent of 0.1 to 25 parts by weight of sulfur, or a mixture of sulfur and a sulfur donor to an equivalent total of 0.1 to 25 parts by weight of sulfur; or (b2) 0.1 to 20 parts by weight, preferably 1 -15 parts by weight of a peroxide; and (c) 0.1 to 20 parts by weight, preferably 0.5-10 parts by weight of the aramid particle.
