Cyclo olefin: Cyclo-Olefin Copolymer, referred as COC, is a transparent and highly pure amorphous resin synthesized by copolymerization of cyclic olefin and ethylene or α-olefin.

Polyisoprene latex (IR Latex) is a polyisoprene rubber latex made by emulsification.

waterborne resin emulsion is a waterborne resin made of carbon five petroleum resin as the basic raw material and emulsified.

Norbornene is an important comonomer, which can be used to prepare cyclic olefin copolymer by non-ring-opening polymerization reaction with a-olefins such as  ethylene, propylene and styrene under the action of Ziegler-Natta or metallocene catalyst.It is also an important synthetic monomer for high-end optical materials and medical pre-filling equipment.
