Abstract

The invention discloses a catalyst, which comprises a foamed ceramic carrier and a hydrogenated main active component. In the catalyst, foamed ceramics serving as the catalyst carrier are used for loading the hydrogenated main active component, and the foamed ceramic carrier is of a porous structure and has good fluid permeability. The invention further discloses a preparation method for the catalyst, and a preparation method for a cyclohexane ethylene homopolymer or copolymer. In the preparation method, polymer solution of a polystyrene or styrene copolymer can be hydrogenated under certain conditions by selecting the special monolithic catalyst, and the catalyst can be simply separated from reaction solution so that the cyclohexane ethylene homopolymer or copolymer is obtained.

Description

technical field [0001] The invention specifically relates to a preparation method of a homopolymer or a copolymer of cyclohexylethylene and a catalyst. Background technique [0002] Polymer resin has played a huge role in people's daily life and social progress. With the development of society, the demand for the performance of polymer materials is also getting higher and higher. Cyclohexylethylene homopolymers and copolymers are a class of high-performance new polymers with broad application prospects. Cyclohexylethylene homopolymer-polycyclohexylethylene (PCHE) has the advantages of high light transmittance, light weight, high glass transition temperature, low water absorption, good optical properties, high strength, and easy molding. Compared with the widely used polycarbonate (PC) material, it has obvious advantages. As shown in Table 1, the glass transition temperature of PCHE is close to that of PC, the density is 21% lower than that of PC, the light transmittance is...
