ABSTRACT:
Multi-armed macromonomers containing multiple side chains attached to a siloxy-containing core terminated on each end with one or more first substantially linear polysiloxane radicals having a polymerizable ethylenically unsaturated-containing terminal group, wherein each side chain comprises a second substantially linear polysiloxane radical having a polymerizable ethylenically unsaturated-containing terminal group are disclosed. Biomedical devices such as contact lenses formed from the multi-armed macromonomers are also disclosed.
