Abstract

The present invention provides a preparation method of supermacroporous polymer microsphere and its product. It is characterized by that said preparation method includes the following steps: adding high-content surfactant into oil phase containing monomer, making the oil phase containing monomer and surfactant be dispersed in water phase, making the above-mentioned material undergo the process of suspension polymerization so as to obtain supermacroporous microsphere. The grain size of said microsphere is 1-200 micrometers, and its porosity is 10%-90%.

Description

field of invention

[0001] The invention belongs to the interdisciplinary field of polymer materials and biochemical industry, relates to a method for manufacturing macroporous polymer microspheres, in particular to a method for preparing super-macroporous polymer microspheres with two types of pore distribution. Background of the invention

[0002] With the development of life sciences, the separation of related biomacromolecules has become an extremely important topic. At present, the separation and purification technology for large-scale preparation of proteins has become a limiting factor in the development of biotechnology. A lot of research is going on at home and abroad, and this direction has also become one of the focuses of scientific and technological investment.

[0003] Although the research on bioseparation media has a history of several decades, the performance of the media (such as mechanical strength, scope of application and service life) and its separation ...
