This disclosure relates to polymerizable silicone compositions, methods for polymerizing such compositions, and to polymerized silicone compositions formed thereby. In one embodiment, a polymerizable composition includes one or more first organosiloxanes or organosilanes, each comprising a plurality of silicon hydride functional groups, one or more second organosiloxanes or organosilanes, each comprising a plurality of reactive heterocycloalkyl functional groups; and one or more third organosiloxanes or organosilanes, each comprising at least about one silicon hydride functional group and at least about one reactive heterocycloalkyl functional group; one or more reactive organic compounds, each comprising at least about one reactive heterocycloalkyl functional group; and an effective amount of a borane catalyst, present, for example, in an amount within the range of 0.0005 wt % to about 10 wt %, wherein the ratio of reactive heterocycloalkyl functional groups to reactive silicon hydride functional groups in the composition is in the range of 1:5 to 5:1.
