Cyclic olefin copolymer (COC) is an amorphous polymer made by several polymer manufacturers. COC is a relatively new class of polymers as compared to commodities such as polypropylene …

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 …

Over the last couple of decades, a new class of polymers called cyclo olefin copolymers (COC) or cyclic olefin copolymers (COC) has been introduced. They have made significant inroads in …

Jan 26, 2025 · Compared with common water-soluble polymers, cycloolefin copolymers (COC) show outstanding hydrophobicity and higher rigidity, even at elevated temperatures, being as …

Cyclic olefin copolymers (COC) are amorphous, transparent thermoplastics composed of cyclic olefin monomers (norbornene) and linear olefins (ethene).

Exceptionally transparent to UV and visible light, TOPAS cycloolefin copolymer is the clear choice for diagnostic applications and analytical testing. We produce TOPAS grades with …

Apr 13, 2004 · ZEON’s cyclo-olefin polymer is an amorphous polyolefin with a bulky ring structure in the main chain, based on DCPD as the main monomer saturating the double bond in …

Mar 13, 2013 · A brief review of historical aspects and of the state of the art of cycloolefin polymerization by ROMP and via addition of cycloolefin copolymerization is presented here.

Cyclic Olefin Copolymers (COC) are a novel type of macromolecular material that is characterized by the copolymerization of cyclic olefin and olefin monomers. This paper provides a review of …

Cyclic olefin (co-)polymer provides a high-temperature alternative to acrylic. Its refractive index and transmittance are similar but the heat distortion temperature is about 30°C higher than for …
