Abstract
Cyclic olefin copolymers are important in polymer material due to their high transparency, good thermal stability, mechanical strength and easy to make film. The hydrophobic cyclic olefin copolymers were not compatible with hydrophilic material and have less chemical attraction each other. Therefore scientists develop many polymerization technology,which contain the grafting polymerization, blocking polymerization, and direct copolymerization with polar monomer, Most of them are grafting polymerization or blocking polymerization, since they contain the function of group and also maintain polymer orginal properties. We expect to improve polymer applications and bring on the material apply to the different domain. This experiments are carried by using the unsaturated alkene alkyl radical on poly[E-co-ENB-co-norbornene] and the hydrogen chloride watery solution. After the reaction the Cyclic olefin copolymers contain Cl group, The grafting of PMMA and PBA are used by atomic transfer radical polymerization methol. The reactions in different temperature, the catalyst system, and the solvent are discussed. At the same time, the products are identified by 1H-NMR, FT-IR, DSC. Theproperties of Cyclic olefin copolymers are studied by using of GPC, UV-VIS, and Contact Angle .
