Curable fluoropolymer containing repeating units derived from VDF and TFE and at least one other fluorinated comonomer and further containing -CF 2 CH 2 I end groups and branching sites derived from one or more perfluorinated bisolefinic ether(s) used as modifier(s), wherein the one or more perfluorinated bisolefinic ether(s) used as modifier(s) correspond to the general formula: CF 2= CF-(CF 2 ) n -O-(R 1 )-O-(CF 2 ) m CF=CF 2 wherein n and m are independent from each other either 1 or 0 and wherein R 1 represents a perfluorinated linear or branched, cyclic or acyclic aliphatic or aromatic hydrocarbon residue that may be interrupted by one or more oxygen atoms and comprises up to 30 carbon atoms. Further provided are methods of making the curable fluoropolymers and for making an article containing the curable polymers.
摘要:
Described herein is a method for coating optical fiber where the coating has been cured by application of a source of monochromatic actinic radiation, such as a light emitting diode, wherein the coating contains a urethane(meth)acrylate oligomer; a (meth)acrylate diluent monomer; a diluent monomer having an electron donating group adjacent to the vinyl group, such as a vinyl ether monomer; and a photoinitiator. Also described are compositions which are capable of undergoing photopolymerization when coated on an optical fiber and when irradiated by a light emitting diode (LED) with improved surface cure and reduced yellowing. Also described are the coated optical fibers produced by such processes and compositions.

摘要:
A synthetic route to polymers comprised of at least two monomers each with a very different reactivity ratio by using a corresponding crosslink agent for each monomer. Novel crosslink agents are described that provide for the copolymerization of at least one hydrophilic monomer with at least one lens monomer typically used to prepare materials for ophthalmic lenses. The new crosslink agents have a relatively high selectivity for the hydrophilic monomer and limited reactivity with the crosslink agent used to polymerize the lens monomer.
