Problems solved by technology

At the present stage, the research on COC basically focuses on the synthesis of COC and the modification of new pure COC. For PCR-grade COC materials, because they are usually co-extruded with LLDPE films, it is difficult to separate them by infrared and NMR during recycling. The high transparency of COC and the presence of LLDPE lead to low rigidity and toughness of PCR-grade COC materials, which limits the application of PCR-grade COC materials, and there is basically no research on its modification.

Abstract

The invention relates to a high-modulus and high-toughness cycloolefin copolymer material and a preparation method thereof. The high-modulus and high-toughness cycloolefin copolymer material comprises a PCR (Polymerase Chain Reaction)-grade cycloolefin copolymer, a thermoplastic elastomer, talcum powder and a processing aid. The cycloolefin copolymer disclosed by the invention has relatively high rigidity and toughness and also has excellent chemical resistance; and meanwhile, the preparation of the material also conforms to the current concept of environmental protection.

Description

technical field [0001] The invention belongs to the field of polymer materials, in particular to a high-modulus and high-toughness cyclic olefin copolymer material and a preparation method thereof. Background technique [0002] Cyclo-Olefin Copolymer (COC for short) is a thermoplastic amorphous transparent polymer material obtained by copolymerizing cycloolefin monomer and α-olefin. Generally speaking, cyclic olefin copolymer refers to the copolymer of cyclic olefin and ethylene, which is prepared by Ziegler-Natta and metallocene catalyzed polymerization. Compared with traditional polyolefin materials such as polyethylene and polypropylene, cyclic olefin copolymer has unique and excellent properties, such as excellent optical properties, its light transmittance can reach 91%, and it has low birefringence and High ampere number, low dielectric constant and dielectric loss, good dimensional stability and high strength, widely used in optical devices, packaging, medical and el...
