A method for preparing a copolymer that involves polymerizing at least one branched alkene monomer and at least one olefin monomer having a pendant benzocyclobutene (BCB) group to form a copolymer comprising a random distribution of a plurality of constitutional units corresponding to the at least one branched alkene monomer and the at least one olefin monomer. The polymerizing includes a carbocationic polymerization reaction involving sequential addition of a plurality of mixtures without terminating the carbocationic polymerization reaction, wherein the plurality of mixtures includes a mixture that includes the at least one branched alkene monomer and does not include the at least one olefin monomer having a pendant BCB group and a mixture that includes both the at least one branched alkene monomer and the at least one olefin monomer having a pendant BCB group. The copolymer composition can undergo crosslinking at elevated temperatures (preferably above 180&#xb0; C.).

Crosslinked polyolefins for biomedical applications and method of making same

The invention relates to a polymer composition that includes a branched alkene which is cationically polymerizable as well as a glass-forming comonomer and/or a vinyl comonomer containing benzocyclobutene as the pendant group. The structure of the polymer composition can take various forms: linear random copolymer, linear block copolymer, star random copolymer, star block copolymer, and other hyperbranched polymers. The copolymer composition can undergoes crosslinking at elevated temperatures (preferably above 180&#xb0; C.).

A method of making an ocular lens device (and resulting lens device) from a polyolefin copolymer material having a crosslinking component, wherein the material is processed to remove unwanted reaction byproducts that can contribute to reduced transparency of the polyolefin copolymer material in the ocular environment of the eye.
