Abstract
Peroxide-curable fluoroelastomeric compositions, consisting of a fluoroelastomer containing bromine, an organic peroxide and a metal-organic hydride having the formula: ##STR1## wherein M is selected from Sn, Si, Ge, Pb; x is an integer from 1 to 3; y, z are zero or integers from 1 to 3, with the proviso y+z=4-x; w is an integer from 1 to 3; the R groups, equal to or different from each other, are selected from: alkyls C.sub.1 -C.sub.4, aryls C.sub.6 -C.sub.12, arylalkyls and alkylaryls C.sub.7 -C.sub.14, optionally containing nitrile and/or hydroxyl groups. The hydride addition allows to increase the curing rate, obtaining at the same time a high crosslinking degree.
