The blending of the most common polyolefins (polyethylene and polypropylene) with
cycloolefin copolymers (COC) has recently been studied in order to improve their dimensional stability and overall performance [4-6].
Cycloolefin copolymers (COCs) form a new class of copolymers which possess excellent properties, such as totally amorphous structure, a high glass transition temperature, excellent mechanical and optical properties, high decomposition temperature, and good moisture barrier, making them a potential replacement in some engineering polymers.
* The vial body, which is made of
cycloolefin co-polymer (COC) and the stopper, which is made of thermoplastic elastomer (TPE) are molded in an ISO Class 5 clean room at the same time and assembled by robots, resulting in a closed vial with ISO Class 5 environment inside, hence the absence of the washing process.
The CD is manufactured by injection molding using a
cycloolefin polymer.
Cycloolefin copolymers (COCs) are new types of amorphous engineering thermoplastics obtained from the copolymerization of ethylene and cyclic olefins.
has signed an agreement to sell it
cycloolefin copolymer (COC) business to a joint venture formed by Daicel Chemical Industries, Ltd., and Polyplastics Co., Ltd., both based in Japan.
Capture probes (13mer) for the 10 most common mutations of K-ras codons 12 and 13 were immobilized on the surface of a new
cycloolefin polymer with optical transparency and background fluorescence comparable to Pyrex glass as described previously (14).
Topas
cycloolefin copolymer (COC), a shrink-sleeve polymer for PET (polyethylene terephthalate) bottles, provides for high-quality labeling by closely following a bottle's shape without creasing, according to Ticona, the technical polymers business of Celanese AG.
Cycloolefin copolymers (COC) was Topas 8007S, commercial copolymer of ethylene and norbornene with 30 mol% of norbornene, Topas Advanced Polymers GmbH, Germany, with density = 1020 kg/[m.sup.3] and MFI = 10.3 g/10 min (230[degrees]C, 2.16 kg).
Hoechst is researching and testing (in an ongoing development program with Mitsui Petrochemical) its
cycloolefin copolymer Topas, produced with metallocene catalysts.
