Novel methods and materials particularly useful for ophthalmic applications and to methods for making and using the same are disclosed herein. More particularly, relatively soft, optically transparent, foldable, high refractive index materials particularly suited for use in the production of intraocular lenses, contact lenses, and other ocular implants and to methods for manufacturing and implanting IOLs made therefrom are disclosed.

This invention relates to a process for forming a long-chain branched polymer and a long-chain branched polymer resulting from the process. The process comprises reacting (a) a polyolefin base polymer with (b) a coupling agent comprising a polymeric coupling agent, optionally blended with a molecular coupling agent, the polymeric coupling agent being a modified polyolefin having a reactive coupling group at one or more terminal ends of the modified polyolefin chain, to couple the polyolefin base polymer (a) with the coupling agent (b) to form a long-chain branched polymer having a long-chain branching and/or higher surface energy relative to the polyolefin base polymer.

Various polycycloolefinic polymers containing phenolic pendent groups and compositions thereof useful for forming self-imageable films encompassing such polymers are disclosed. Such polymers encompass norbornene-type repeating units containing phenolic pendent groups which contain very low levels of fluorine containing monomers. The films formed from such polymer compositions provide self imageable, low-k, thermally stable layers for use in microelectronic and optoelectronic devices.

Embodiments in accordance with the present invention encompass compositions encompassing a procatalyst and a thermal or photoactivator along with one or more monomers which undergo vinyl addition polymerization when said composition is heated to a temperature from 50 C. to 100 C. to form a substantially transparent film. The monomers employed therein have a range of refractive index from 1.4 to 1.6 and thus these compositions can be tailored to form transparent films of varied refractive indices. Accordingly, compositions of this invention are useful in various opto-electronic applications, including as coatings, encapsulants, fillers, leveling agents, among others.
