Problems solved by technology

The catalytic activity of these simulated enzymes not only cannot match that of natural enzymes, but is even significantly lower than that of the corresponding small molecule catalysts. The catalytic group inside the molecule makes the catalytic group unable to effectively perform the catalytic performance, which is the so-called "accessibility problem"
The problem of accessibility is a problem that has plagued many polymer catalysts so far and it is difficult to achieve industrial applications.

Abstract

The intelligent catalyst consists of vinyl imidazole 20-40 wt%, 2-acrylic amino-2-methyl-1-propyl sulfonic acid 20-40 wt%, and N, N-methylene-diacrylamide 11-22 wt% to form crosslinked polymer compound as well as additive reagent 9-18 wt%. Its preparation includes the steps of: free radical emulsion polymerization of vinyl imidazole, 2-acrylic amino-2-methyl-1-propyl sulfonic acid, and N, N-methylene-diacrylamide to form crosslinked electric response intelligent polymer catalyst; and the test of the catalytic activity. The present invention has the advantages of the flexibility and mobility introduced into the catalyst structure to solve the problem of the polymer catalyst in accessibility and to raise the activity; and the capacity of using the catalyst as artificial enzyme model to simulate the flexibility of enzyme.

Description

[0001] (1) Fields: [0002] The invention belongs to a polymer catalyst and a preparation method thereof, in particular to an electric response intelligent polymer catalyst and a preparation method thereof. (two) background technology: [0003] Currently, in the field of protein function research, the mechanism of high catalytic activity of enzyme proteins is a so far unsolved problem. With the deepening of protein structure research and catalyst theory research, various speculations and hypotheses about the catalytic mechanism of enzymes have been frequently proposed, but the theoretical basis is still based on the "lock-key" model and induced fit model proposed earlier. However, these two models are only qualitative descriptions of the enzyme mechanism, and do not give precise quantitative or semi-quantitative predictability. The low success rate of computer-aided drug design and discovery further shows that the above two models are not strictly valid. That is to say, in a...
