    Abstract: The present disclosure relates generally to photocurable compositions and methods for continuously forming a three-dimensional body from these compositions. More particularly, the present disclosure relates to photocurable compositions comprising a mixture of polysiloxanes capable of being dually cured, i.e., first by UV radiation followed by thermal treatment, or being cured by UV radiation. In one aspect, the disclosure provides a photocurable composition, including: a first polysiloxane comprising at least two acrylate or methacrylate groups per molecule; a second polysiloxane containing at least one (e.g., at least two) Si—H group per molecule; a third polysiloxane containing at least one (e.g., at least two) reactive aliphatic ethylene group per molecule; a free radical photoinitiator in an amount of about 0.01 to about 10 weight % based on the total weight of (meth)acrylate-containing polysiloxane in the composition; and a hydrosilylation catalyst in an amount of about 0.001 to about 10 weight % hydride-containing polysiloxane and vinyl-containing polysiloxane in the composition.

    Abstract: 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.
