WebHence, to circumvent these issues, herein we describe the development of a cyclo olefin polymer (COP)-based MPS using photobonding processes and vacuum ultraviolet (VUV), designated as COP-VUV-MPS. COP is an amorphous polymer with chemical/physical stability, high purity and optical clarity. Due to the thermostability and high modulus of … In organic chemistry, a cycloalkene or cycloolefin is a type of alkene hydrocarbon which contains a closed ring of carbon atoms and either one or more double bonds, but has no aromatic character. Some cycloalkenes, such as cyclobutene and cyclopentene, can be used as monomers to produce … See more Cycloalkenes follow a similar nomenclature system to alkenes, but the carbons are numbered starting at a carbon on the double bond and then through the double bond and around the ring. This method is used to keep the … See more Ring Closing Metathesis Ring-Closing Metathesis switches out functional groups from one or multiple terminal alkenes to … See more • Perfluorocycloalkene (PFCA) • Alicyclic compound • Olefin See more Cycloalkenes with a small ring have about 20° more bond angle strain than a cycloalkane of the same size. This is because the bond … See more As previously mentioned, cis-isomers of cycloalkenes exhibit more stability than trans-isomers; however, on an experimental and computational level, this property is only applicable to cycloalkenes with 10 carbons or less. As the number of carbons increase, … See more
