Embodiment

[0272] The following examples will be used to illustrate the present invention in further detail, but the present invention is not limited to these examples.

[0273] The measurement or evaluation of each physical property in an Example and a comparative example was performed as follows.

[0274]1. The content of structural unit B existing in the form of diads

[0275] The content of structural unit B in the copolymer is passed 13 C-NMR measurement.

[0276] In the following examples, ethylene was used as the alkene and norbornene was used as the cyclic olefin. For the resulting ethylene-norbornene copolymer, refer to figure 1 , the content of the structural unit B existing in the form of diads is calculated as follows.

Abstract

The invention relates to a chain olefin-cycloolefin copolymer. According to the invention, content of cycloolefin in the chain olefin-cycloolefin copolymer is adjusted, and the copolymer contains diad formed by direct bonding of two cycloolefin constitutional units. Then, the obtained copolymer can show good properties in tensile strength, elongation at break, processability and the like. The chain olefin-cycloolefin copolymer can be used in manufacturing a polymer composition. The chain olefin-cycloolefin copolymer and the polymer composition can be used in manufacturing optical components, packing materials, electronic components, medical instruments and the like.

Description

technical field [0001] The invention relates to an alkene-cycloolefin copolymer and its application, and also relates to a polymer composition comprising the alkene-cycloolefin copolymer and its application. Background technique [0002] With the continuous progress of society and the rapid development of science and technology, the demand for high-performance materials is also increasing. Olefin-cycloolefin copolymers, especially ethylene-cycloolefin copolymers, are excellent amorphous thermoplastic polymer materials with high transparency, low water absorption, high heat resistance and high refractive index. As one of the high-end products of C5 series comprehensive utilization, it is expected to replace PC and PMMA in optical components. In addition, this material may also have a potentially huge market in the fields of packaging, electronic components, medical appliances, etc. [0003] Usually the catalysts used to make ethylene-cycloolefin copolymers are metallocene c...
