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 and polyethylene. This newer material is used in a wide variety of applications including packaging films, lenses, vials, displays, and medical devices. In 2005 there were "several types of commercial cyclic olefin copolymers based on different types of cyclic monomers and polymerization methods.

Macrocyclic polymers, defined as polymers having more than 20 atoms in a ring .

Macrocyclic polymers, defined as polymers having more than 20 atoms in a ring structure, have been known for many decades. The diketone monomer has low solubility in DMF, and high dilution conditions were obtained by adding the solid reactants in portions during the course of the reaction. The cyclic ether ketone oligomers were also transformed into cyclic ether phthalazines by reaction with hydrazine.

Abstract While chemically different monomers can be mixed, the mixing of the corresponding polymers in the solid state usually results in (multiphase) polyblends. Even the mixing of two differen. More).

The polymerization of cyclic three-member rings monomers is performed using ionic type initiators

The polymerization of cyclic three-member rings monomers is performed using ionic type initiators  . Part of the NATO Advanced Study Institutes Series book series (ASIC, volume 51). Abstract. The polymerization of cyclic three-member rings monomers is performed using ionic type initiators. Anionic and cationic polymerization produce generally random amorphous polymers very often of low molecular weight. Some properties will vary due to monomer content. The high flow of COC enables higher aspect ratio (large yet thin) optical component fabrication than other optical polymers. High ultraviolet transmission is a hallmark of COC materials, with optimized grades the leading polymer alternatives to quartz glass in analytical and diagnostic applications. These include glass transition temperature, viscosity, and stiffness.

Materials with elastomeric properties or tactic polymers with high glass transition temperatures and melting points are obtained with a wide range of microstructures. Cyclic olefin copolymers are produced by chain copolymerization of cyclic monomers such as 8,9,10-trinorborn-2-ene (norbornene) or 1,2,3,4,4a,5,8,8a-octahydro-1,4:5,ne (tetracyclododecene) with ethene (such as TOPAS Advanced Polymer's TOPAS, Mitsui Chemical’s APEL), or by ring-opening metathesis polymerization of various cyclic monomers.
