Abstract

The invention relates to the field of polymer catalysts, and discloses a composition for removing a catalyst in titanium-based isoprene rubber and an application of the composition. The composition contains a component A and N,N'-bis(3-aminopropyl)ethylenediamine, wherein, the component A is at least one selected from a group consisting of alcohol amine, aliphatic monoamine, aromatic monoamine, aromatic diamine, aromatic polyamine and compounds represented as a formula (I), and in the formula (I), the n is an integer selected from 1 to 8. With the adoption of the method provided by the invention, the catalyst in the titanium-based isoprene rubber can be removed, the removal efficiency is high, and the obtained titanium-based isoprene rubber has excellent processing and application performances.

Description

technical field [0001] The invention relates to the field of polymer catalysts, in particular to a composition for removing titanium-based isoprene rubber catalysts and a method for removing titanium-based isoprene rubber catalysts. Background technique [0002] Polyisoprene can be divided into cis-1,4-polyisoprene, trans-1,4-polyisoprene, 3,4-polyisoprene and 1,2-polyisoprene pentadiene. Among them, cis-1,4-polyisoprene is commonly known as isoprene rubber, and its microstructure is similar to natural rubber (such as Hevea, guayule). At present, isoprene rubber has been widely used in the manufacture of tires and other rubber products, and is the main substitute of natural rubber. [0003] Due to the high degree of unsaturation of cis-1,4-polyisoprene, its molecular chain is easily broken and degraded under the action of some physical and chemical factors such as oxygen, ozone, light, high temperature and ultraviolet rays. At present, Ziegler-Natta catalysts are usually ...
