preparation example 1

[0053] Fully replace the reaction system with high-purity nitrogen, and add 0.03M WOCl to it 4 100mL of toluene solution, then add 60mL of 0.05M tetrachlorophenol toluene solution and 20mL of 0.45M 1-butene toluene solution under stirring, keep the system temperature at 20°C, and age the resulting mixture at a stirring speed of 200r / min After 30 minutes, the color of the solution was observed to change from dark blue to purple, and catalyst solution A was obtained.

[0054] It is calculated that the molar ratio of the main catalyst component, the oxygen- or halogen-containing activator and the linear monoolefin in the catalyst solution is 1.0:1.0:3.0. .

preparation example 2

[0056] Fully replace the reaction system with high-purity nitrogen, and add 0.05M WCl to it 6 100mL of toluene solution of benzoyl peroxide, and then add 83.3mL of 0.03M benzoyl peroxide toluene solution and 50mL of 0.05M 1-hexene xylene solution under stirring. Aged for 60 minutes at a constant stirring speed, observed that the color of the solution changed from dark blue to purple, and obtained catalyst solution B.

[0057]It is calculated that the molar ratio of main catalyst component, oxygen or halogen-containing activator and linear monoolefin in the catalyst solution is 1:0.5:0.5.

preparation example 3

[0059] Fully replace the reaction system with high-purity nitrogen, and add 0.04M MoBr to it 5 100mL of toluene solution of 1-octene, and then add 120mL of 0.05M epichlorohydrin toluene solution and 2mL of 4.0M 1-octene benzene solution under stirring. Aged for 20 minutes to obtain catalyst solution C.

[0060] It is calculated that the molar ratio of main catalyst component, oxygen or halogen-containing activator and linear monoolefin in the catalyst solution is 1:1.5:2.0.

Abstract

The present invention relates to the field of rubbers, particularly to a liquid trans-polycyclopentene rubber, a preparation method and applications thereof, wherein the number average molecular weight is 800-60000, the molecular weight distribution index is 1.1-3.5, the straight chain structure content in the polymer is more than 99 wt%, the trans structure content is more than 70 wt%, the glass transition temperature is less than -85 DEG C, and the gel content is less than 0.02 wt%. According to the present invention, the liquid trans-polycyclopentene rubber has the inherent excellent characteristics of the liquid rubber, the rubber prepared by mixing the liquid trans-polycyclopentene rubber and other types of rubbers can provide performances of good processability, good extrusion performance, good low-temperature resistance, high resilience, low heat-generation, high wear resistance and the like, and the catalyst preparation step and the rubber preparation process are separated in the liquid trans-polycyclopentene rubber preparation method, such that the stable product catalyst can be separately prepared and can be prepared in advance and is easy to store, and the method is suitable for industrial production.

Description

technical field [0001] The invention relates to the field of rubber, in particular to a liquid trans polycyclopentene rubber, a preparation method and an application of the liquid trans polycyclopentene rubber. Background technique [0002] Liquid rubber is a viscous, flowable liquid rubber with an index average molecular weight of less than 100,000, and its viscosity changes with the molecular weight and molecular configuration of the polymer. Because of its low molecular weight, fluidity at room temperature and wide range of bulk viscosity, it has many advantages in use, mainly including: easy to operate, can be vulcanized and molded by casting method and injection method, simple equipment, convenient construction, and low energy consumption. Low; can produce various rubber products from rubber shoes, industrial products to tires, etc.; is the best processing aid in the rubber industry, such as plasticizers, softeners, co-vulcanizing agents, modifiers, etc.; plasticizers i...
